"Watch how I can just walk around it and no matter what side I'm on I see the image the same." "He's still looking at me!" Reminds me of walking around the sprites of dead characters in the original Doom.
It's called "billboarding" in rendering terminology. In Doom's case, it used the extremely simple "point billboarding" where it rotates the billboard on all axes - if you could somehow look down the object would still face you.
I've been thinking about these principles recently when I walk my dog past a neighbor's home with a large wood fence with vertical slats. When I stand still I can't see through the fence. There is only about 1/4 inch gap between some of the slats. But when I walk fast enough my brain can put together a pretty clear image of the yard behind the fence.
@airplanes_aren.t_real partly but not exactly. The wood slats of the fence were about 4 inches wide each with only a small space between each. When standing still looking at the fence you wouldn't really see anything behind it, just tiny slivers, but moving past your mind can put each sliver together to form the whole image. Similarly to what's in the video.
I had a similar idea when I was a horny teen. A public bath had horizontal bamboo slats making kind of a venetian blind covering up the window to the women's dressing room. But there were small gaps between the slats. I realized if I mounted enough cameras above and below each other and combined their images (blacking out the parts covered up by the slats), it would combine into an image of the women's dressing room. Academic thought experiment of course. I never actually built it.

This sort of method goes all the way back to the very beginnings of television. Look up "mirror screw" mechanical displays. This sort of thing in the modern context has been well-known for decades.
Most likely because nobody had flat panels containing moving pictures at the time anybody would've been considering this. A static image that could be seen anywhere could've just as easily been a rotating sign.
I was looking for a comment like this. I'm only 58 seconds in right now and I predict it's just a spinning screen with a tiny view angle so it only shows up in your eyes when you see it head on but since it's spinning so fast you see it no matter what angle you're viewing from. Edit: hehehe I was kinda right
An issue is that most of the light is lost in the cylinder that blocks the light.. So, in order to have a sufficiently bright image, you need a very powerful light source and the corresponding power consumption.
...for not a lot of return. Plus the image is inherently narrow. You'd be far better off with just 3-4 regular, static screens mounted around a central pole.
There is no real problem in creating a brighter display for that purpose. Projectors are essentially displays with enormous brightness. The electric motor, however, is more concerning in terms of energy usage and maintenance.
Sweet! I'm all set with my 50" OLED screen. I made a table and slip ring connection so the cord can't rip off. The TV is bolted down so it won't fall over. I have a 2hp 1800rpm single phase motor attached to a 4.5:1 reduction drive to hit 400 rpm. Now to power it on....... Holy S**t that is awesome! I can't see any image at all because the TV ripped itself apart from the 4,000 lb/ft of torque at the edges, but still! 10/10 would spend $4,700 again to see cockamamie explosion!

No, they didn't spin the trees really fast with a mask in front of it. You are thinking of a 2d image which rotates to face the player. The image is facing you and from another angle the illusion would not work.

It would be cool if optional motion tracking (for potentially multiple users) was involved to black out parts of the screen that are definitely not being observed to save on energy and allow the rest of the screen to be brighter, which in turn allows the slit to be narrower and thus the image sharper.
I just tried rotating a 45 degree mirror over my phone display. You'd have to spin the image on the display at the same time. But if you could sync it right you could spin just the slit and the digital image, and keep the physical display device still.
@@barneylaurance1865 I'm wondering if we can take all the mechanics out of it and just make a digital version where it's just a cylindrical display with the pixels following the same framerate pattern around the display as the original. As long as the digital "slit" of viewable pixels rotates around the screen at the same rate as the physical spinning, then it should be the same, no?
@@MrE_That wouldn't work because the slit has to be distanced from the screen. What angle the slit is relative to you determines what part of the image you see
@@MrE_say you had the slit formed by a cylindrical black and white LCD screen, you'd still need the colour screen spinning inside it or you'd still be able to stand at the side of the screen and not see the image.
Ideally they'd both be fed from one network source in any kind of finished product, but for the demo, u1 is probably on the money - two hands pressing play.
simple script in IFTTT on android can synch to googles network timestamp and some players can use shortcuts to jump to the next keyframe within an MPG format video. But for practicality it would be easier to hook one phone to a MIPI board (phones equivalent to HDMI) and then just connect two screens to it.
You say it's unlike anything we've ever seen, yet it's nearly the same principle as one of the fans that spins with lights or a message that flashes. Pretty cool that it's nearly the same tech just inverted.
Inventor/maker of that Riven prop replica here! I actually set out to make the Riven replica first and the display was almost an afterthought! But yes it's my favourite game if you can't tell haha
@@riumplus Woah, great job. I got to speak to Rand Miller directly and asked him about the big dagger that's on the wall of their office (the one Gehn uses to jam the lever at the beginning). He told me a lovely story about how, when Mythbusters started, he checked his phone history and said, "Hey, that's the guys who made the dagger!"
Hey, I know Mike! :D When I saw this video I immediately knew what technology he was talking about. Mike has a number of patents surrounding his invention, and he's willing to license.
It's not going anywhere with moving parts and low brightness. Also I've seen a similar thing with a mirror and a horizontal screen 10+ years ago so I don't know what kind of patent anyone could file on this.
@@dustysparks No it was some kind of 3D display, the image was changing as the mirror rotated so you could see the object from all sides, like a hologram but different. I guess it's not the same as this but I bet there are hundreds of people who invented this before.
This is amazing. Imagine every person in the room being able to see the same thing without the distortion of having the wrong seat on the couch. You could even have this on the center of a table and people seated around it, talking to each other, eating, or playing a game, while being able to see other people's faces sitting across from you and everyone sees the same image.
You always show so many cool things, it's like you have found the infinite well of cool stuff from which it springs forth endlessly. Never thought of a display like this, but it makes sense!
"When Leia delivers her message, some people only see her from the back... so the Andotrope is better in real life..." I dunno man, that depends who you're asking, lol 😊
4:10 No matter how much I know, logically, it is a concave mask, I CANNOT make my brain see it that way. No matter what, it is always a 3D image. It is quite frustrating
I’d think so. It would just raise the frame rate some more,which is a good thing I think. Especially if this goes in more advanced directions, I feel that’s the next step honestly.
This would be fantastic for meetings where everyone is around a table. Instead of everyone having to look at one wall for presentations, it could be right there in the middle of the table.
It's three microscopic zigzag cut pieces of silicon wafer which bend based on the G force. If its spinning, each wafer just stays bent and doesn't get worn out by being bent over and over again.
I was gonna say its a zooatrope modernized 😂 Nice. 2:52 Id bet with a bit of fine tuning you could also use it as a volumetric display as well, making it more versatile
It isn't volumetric because all the pixels you see exist on a single convex curved path. You could make the screen show you different things as you move around it though, using eye tracking. Linus Tech Tips just released a video about a glasses-free 3D monitor that works by eye tracking.
It could be volumetric, because at any point in time each column of pixels on the screen is only visible to observers looking from a certain angle. The flat 2D image on the screen would be super weird, but it would work.
There is a reason it hasn't been used before. First, you're losing a huge percentage of your light because of the slits so the display needs to be correspondingly brighter (contrast may be affected too) plus when do you actually want to watch a cylinder of video? You can't make it much wider without starting to get dangerous/expensive so you basically have a gimmick that might be useful for an advertisement in the airport or at night in vegas (not outside where it would be too bright). But neat video.
what are you talking about? It is literally just a screen inside a cylinder barrier with slits. It is really cheap as there is no weird technology that you need to make it. Screen Nowadays are bright like 2000 nits. Plus, you can actually watch horizontal video, just make the cylinder radius wider. Also it would be not a cylinder video but still normal video
@@youravghuman5231 As you get bigger the footprint of the "display" gets bigger because it's a cylinder; doubling the size of the display squares the space it takes up. That alone would make big displays fairly impractical in public settings. The Andotrope needs to spin 1200RPM for 40fps according to the website. Since I don't see why that would be size dependent, a 1 meter diameter display (0.5m radius) would have its outer edge traveling over 220 kph. That speed is comparable to the edge of a standard 12" tablesaw's blade. So the real questions are, 1) how long can you run all those components under that sort of centrepital force and 2) how strong a transparent shield can you make to contain a "catestrophic failure" scenario from exploding like a grenade? A display that can be seen from every angle but only big enough to be viewed by a few people standing close is going to be limited to some very particular uses; the Princess Leia example is probably being the best case of a few people watching a barbie-doll sized image. Edit: Given all the mechanical complexity, is spinning a single display really going to be that much better than multiple displays arranged facing outward? Four 1m displays in a square takes essentially the same space as the cylinder and no viewer can be more than 45° from center, 6 displays takes an area 2m across with no one more than 30° from centered, (8 displays w/ 2.6m and 22.5°). These won't have "perfect" views from all angles, but pretty good ones considering how small these displays and therefore close the viewers would have to be anyway.
@ Whats expensive is building a *large* display like that for viewing flight info in an airport that's safe and reliable. Sure, you can spin two 55" TVs in your garage pretty cheaply but you want to have 80ish kg spinning at near 3600 rpm on a 4 foot diameter circle for years without breaking and without posing a danger to people nearby (that's a fuckton of mass that could fly out if the cylinder gets unbalanced). Remember, people suck. You will absolutely have idiots or children throwing things at the display to see them wizz out (risking unbalancing it) because of the great speed so you probably need to wrap the whole thing in thick polycarbonate which likely means you need a forklift to install and do maintenance. Since the whole thing spins you need to use those concentric joint things to transmit power which makes it harder to avoid wear and creates another point of failure. Start adding up the lifetime costs and it just doesn't make sense.
The design mimics a screen in the old video game Riven, sequel to Myst. (Peaceful exploring/puzzle solving.) The top of the cage also holds the support bearing that James had the big arm mount for.
I don't get it. When you view both phones from the side, looking right at the edge, how are you seeing either of the images? And why is the image not getting skewed when looking at it from an side angle?
I think the slits in the cylinder are only directly in front of the screens, so the only times you ever actually see the screens is when they’re facing you straight on, then your brain fills in the gaps while it’s obscured (like with a normal monitor’s refresh rate). I am curious about what long term effects the high speed rotation has on the phones/screens though…. 😵💫 (In case it wasn’t clear, the phones are spinning with the cylinder)
@@ThetaGraphics if you needed to be in front of the screen for this to work, you could just look at the screen. but he is showing in the video that he is walking around it more than 90 degrees and it still works, while the phones inside are static
@@OlivioSarikas. The phones are actually not static, they are spinning with the cylinder. (I had edited my first post to clarify this, but it probably didn’t email the update, lol. 🤷♂️)
I had a spinning display built 25 years ago. Same principle. Not a new idea. And it was inspired back in the 80's, when I had a toy button on a string with a bird on one side and a cage on the other. What was amazing to me, was not that the bird appeared inside the cage when spun, but that the picture always faced the observer. At the time there was no tech for such displays, but later I was able to do it with a spinning screen and a projector below. The problem with this tech is that it's noisy, unless you're spinning your screen in a vacuum, and with a slit cylinder, you're doing what a privacy screen filter can do way better, without causing you to sacrifice luminance output. The key principle is still the same as in my machine.
Came here to post a variant of this. Definitely not a remotely new idea, but having a mass produced refined model of some sort would be a little cool for specific applications, especially public displays
this was drastically simpler than I was expecting. I thought it was going to be something that had to do with projecting an image onto multiple discs of mirrors and then orienting them in a way and spinning them rapidly.
Larger versions could be built with projector screens inside so the electronics don't have to experience high rotational g forces. Have the projectors stationary with spinning mirrors
The projector also has to spin along with everything else. A projected image would be a way to have less/smaller hardware inside the system, however, versus a full-size display. There's no setup that would keep the image in place as just one part or the other rotated. Hold a hand mirror and spin it to see the effect. There's nothing you can keep in the reflection unless it moves with the mirror, because reflection angle doubles whatever tilt you introduce. Where the phone display blurs the entire image if it's spun without the slit filter, a mirror (including more appropriate silver movie projector screen) would have the image distort, then go completely out of view when it spun, whether there's a slit in front or not.
This is the future technology the 80s promised me
Well said.

2D sprites in 3D environment games. Like the games in the Doom and Duke Nukem 3D era
@@DarthGTB They're still used widely in games today for particle effects.
Perhaps try a wireless PC monitor, put it on top or below and use peppers ghost reflector which is what spins
I just tried rotating a 45 degree mirror over my phone display. You'd have to spin the image on the display at the same time. But if you could sync it right you could spin just the slit and the digital image, and keep the physical display device still.
@@barneylaurance1865 I'm wondering if we can take all the mechanics out of it and just make a digital version where it's just a cylindrical display with the pixels following the same framerate pattern around the display as the original. As long as the digital "slit" of viewable pixels rotates around the screen at the same rate as the physical spinning, then it should be the same, no?
@@MrE_That wouldn't work because the slit has to be distanced from the screen. What angle the slit is relative to you determines what part of the image you see
@@MrE_say you had the slit formed by a cylindrical black and white LCD screen, you'd still need the colour screen spinning inside it or you'd still be able to stand at the side of the screen and not see the image.
Thanks!

Hi
Ok, dumb question: how do you get the two phones to sync up?
Probably pressed play on both at roughly the same time
ok, I completely overlooked this important detail from the video. You're so right.
Ideally they'd both be fed from one network source in any kind of finished product, but for the demo, u1 is probably on the money - two hands pressing play.
simple script in IFTTT on android can synch to googles network timestamp and some players can use shortcuts to jump to the next keyframe within an MPG format video. But for practicality it would be easier to hook one phone to a MIPI board (phones equivalent to HDMI) and then just connect two screens to it.

Me: Mum, I wanna fight the Sprites in the new Doom
Mum: We have Doom at home.
I think you're super cool and your channel is super cool.
You say it's unlike anything we've ever seen, yet it's nearly the same principle as one of the fans that spins with lights or a message that flashes.
Pretty cool that it's nearly the same tech just inverted.
2:08 The guy who invented this must be a fan of Riven.
I yelled at the screen. I was so happy to see that
Had the same thought lol
I think it was a brilliant artistic choice. You've got to stop people from touching the spinning bits anyway, so why not do it in style?
Inventor/maker of that Riven prop replica here! I actually set out to make the Riven replica first and the display was almost an afterthought! But yes it's my favourite game if you can't tell haha
@@riumplus Woah, great job. I got to speak to Rand Miller directly and asked him about the big dagger that's on the wall of their office (the one Gehn uses to jam the lever at the beginning). He told me a lovely story about how, when Mythbusters started, he checked his phone history and said, "Hey, that's the guys who made the dagger!"
Suddenly nostalgic for Doom 2, where all the creature sprites were front-facing even when you walk around them in '3D' space.

You're not just a science genius. You're a marketing genius. Congratulations. Love your channel.
Hey, I know Mike! :D When I saw this video I immediately knew what technology he was talking about. Mike has a number of patents surrounding his invention, and he's willing to license.
It's not going anywhere with moving parts and low brightness.
Also I've seen a similar thing with a mirror and a horizontal screen 10+ years ago so I don't know what kind of patent anyone could file on this.
Can you patent this?
@@Milan_Openfeint Are you talking about pepper's ghost illusion? Because that's 100 years old and only works from the front.
@@dustysparks No it was some kind of 3D display, the image was changing as the mirror rotated so you could see the object from all sides, like a hologram but different. I guess it's not the same as this but I bet there are hundreds of people who invented this before.
This is amazing. Imagine every person in the room being able to see the same thing without the distortion of having the wrong seat on the couch.
You could even have this on the center of a table and people seated around it, talking to each other, eating, or playing a game, while being able to see other people's faces sitting across from you and everyone sees the same image.
This helps us play Doom in real life.

You always show so many cool things, it's like you have found the infinite well of cool stuff from which it springs forth endlessly. Never thought of a display like this, but it makes sense!
2:03 is that the thing from Myst or Riven?
Bro a fellow myst enjoyer less gooo
Riven I think, in the "school" where you learn to count
I'm glad I wasn't the only person who recognised it! It's from Riven!
This is like billboarding. Like the trees in Mario 64 or the barrels in Doom, which are 2D sprites which always directly face towards the player(s).
"When Leia delivers her message, some people only see her from the back... so the Andotrope is better in real life..."
I dunno man, that depends who you're asking, lol 😊
This looks like a great attention prompting device device, I think we will see more of these. Thank you The Action Lab.
4:10 No matter how much I know, logically, it is a concave mask, I CANNOT make my brain see it that way. No matter what, it is always a 3D image. It is quite frustrating
That means you have a strong preference for seeing faces as real. Less likely you are autistic.
Blur your eyes a bit and try to conceptualize and visualize the concave 3D object as a whole object at the same time.
I actually can’t see the effect at all. It just looks like the inside of a mask to me
So strange, I can definitely see it but I have to focus.
I can only tell by looking at the edges or sides by the hair that it’s the concave side
Damn its like doom where every sprite is facing you no matter where you look at it from
If you pause the video at 0:33 then step one frame at a time (comma and period keys), you can see when the image is blocked by the cylinder.
I don’t see it. I think you’re confused by the frame rate issue.
At 1:17 he explains it.
This would be cool in airports or malls.
Always a great vid
You haven't even watched the whole thing!
Brilliant. Now we need screens that we can't see from any angle!
With a big enough cylinder, could you use more than 2 screens?
I’d think so. It would just raise the frame rate some more,which is a good thing I think. Especially if this goes in more advanced directions, I feel that’s the next step honestly.
So much easier than getting two monitors and running around in circles all day to get the same effect like I've been doing for years.
Since it's very fitting for the flat sprite style: can it run Doom?
yes, easily you run parsec on both screens and play off a pc
Real life Doom sprites coming to a reality near you.
This is like the book of an enchantment table
This would be fantastic for meetings where everyone is around a table. Instead of everyone having to look at one wall for presentations, it could be right there in the middle of the table.
Cue a thousand bosses making bad jokes about being omnipresent.
The poor phone accelerometer 😂
🤣 "The compass app just keeps showing 'F*** you'."
accelerometer in integrated circuit is actually just force sensors, so they can take some abuse
It's three microscopic zigzag cut pieces of silicon wafer which bend based on the G force. If its spinning, each wafer just stays bent and doesn't get worn out by being bent over and over again.
thank you for the gift. 3d printing is the only way a you tuber can gift their views an a actual physical gift
The Mona Lisa of screens 👁 💋 👁 always watching

Thank you for showing this clever invention, I can't believe I missed it at Open Sauce!
I was gonna say its a zooatrope modernized 😂 Nice. 2:52
Id bet with a bit of fine tuning you could also use it as a volumetric display as well, making it more versatile
It isn't volumetric because all the pixels you see exist on a single convex curved path. You could make the screen show you different things as you move around it though, using eye tracking. Linus Tech Tips just released a video about a glasses-free 3D monitor that works by eye tracking.
It could be volumetric, because at any point in time each column of pixels on the screen is only visible to observers looking from a certain angle. The flat 2D image on the screen would be super weird, but it would work.
Like in Doom 1 and 2 when you killed an imp and their black single-pixel, omnidirectional fudge hole was visible from any angle.
There is a reason it hasn't been used before. First, you're losing a huge percentage of your light because of the slits so the display needs to be correspondingly brighter (contrast may be affected too) plus when do you actually want to watch a cylinder of video?
You can't make it much wider without starting to get dangerous/expensive so you basically have a gimmick that might be useful for an advertisement in the airport or at night in vegas (not outside where it would be too bright).
But neat video.
what are you talking about? It is literally just a screen inside a cylinder barrier with slits. It is really cheap as there is no weird technology that you need to make it. Screen Nowadays are bright like 2000 nits.
Plus, you can actually watch horizontal video, just make the cylinder radius wider. Also it would be not a cylinder video but still normal video
@@youravghuman5231 Plus, the way shown here is just vertical video. Pretty sure it's more prevalent than "Cylinder video" would be lol
@@youravghuman5231 As you get bigger the footprint of the "display" gets bigger because it's a cylinder; doubling the size of the display squares the space it takes up. That alone would make big displays fairly impractical in public settings.
The Andotrope needs to spin 1200RPM for 40fps according to the website. Since I don't see why that would be size dependent, a 1 meter diameter display (0.5m radius) would have its outer edge traveling over 220 kph. That speed is comparable to the edge of a standard 12" tablesaw's blade.
So the real questions are, 1) how long can you run all those components under that sort of centrepital force and 2) how strong a transparent shield can you make to contain a "catestrophic failure" scenario from exploding like a grenade?
A display that can be seen from every angle but only big enough to be viewed by a few people standing close is going to be limited to some very particular uses; the Princess Leia example is probably being the best case of a few people watching a barbie-doll sized image.
Edit: Given all the mechanical complexity, is spinning a single display really going to be that much better than multiple displays arranged facing outward? Four 1m displays in a square takes essentially the same space as the cylinder and no viewer can be more than 45° from center, 6 displays takes an area 2m across with no one more than 30° from centered, (8 displays w/ 2.6m and 22.5°). These won't have "perfect" views from all angles, but pretty good ones considering how small these displays and therefore close the viewers would have to be anyway.
@ Whats expensive is building a *large* display like that for viewing flight info in an airport that's safe and reliable.
Sure, you can spin two 55" TVs in your garage pretty cheaply but you want to have 80ish kg spinning at near 3600 rpm on a 4 foot diameter circle for years without breaking and without posing a danger to people nearby (that's a fuckton of mass that could fly out if the cylinder gets unbalanced).
Remember, people suck. You will absolutely have idiots or children throwing things at the display to see them wizz out (risking unbalancing it) because of the great speed so you probably need to wrap the whole thing in thick polycarbonate which likely means you need a forklift to install and do maintenance.
Since the whole thing spins you need to use those concentric joint things to transmit power which makes it harder to avoid wear and creates another point of failure. Start adding up the lifetime costs and it just doesn't make sense.
no reason someone can't use lightweight LCD screens for bigger versions of this
This could make for a doom 1 and 2 themed laser tag with enimies that look exactly like they do in game down to being 2.5D
That’s very cool. I can see we he put a cage around it. Inquisitive fingers might get a shock with that spinning at 450rpm 😂
The design mimics a screen in the old video game Riven, sequel to Myst. (Peaceful exploring/puzzle solving.) The top of the cage also holds the support bearing that James had the big arm mount for.
Finally they made Doom sprites IRL
2:09 : this has definitely a Myst/Riven mood
thats because its a direct replica of a prop from riven, playing a recreation of one of the videos in the game haha
That guy's awesome! Thanks for making a video about this, also I find it cute you let your kids make stuff on your 3D printer
That's so coo!
I can see this being implemented into tvs oneday, and some people will set up their livingrooms wit circle sofas around the tv!
Why would you ? We are gonna have super comfortable AR glasses by that point
Unless you're a family of 20 people, that seems completely unnecessary
it'd take up a space equivalent to a cylinder of the TV's half-width. I'm not sure it'd be practical to use for anything but portable TVs
I don't get it. When you view both phones from the side, looking right at the edge, how are you seeing either of the images? And why is the image not getting skewed when looking at it from an side angle?
I know right... What a strange presentation.
I think the slits in the cylinder are only directly in front of the screens, so the only times you ever actually see the screens is when they’re facing you straight on, then your brain fills in the gaps while it’s obscured (like with a normal monitor’s refresh rate). I am curious about what long term effects the high speed rotation has on the phones/screens though…. 😵💫 (In case it wasn’t clear, the phones are spinning with the cylinder)
@@ThetaGraphics if you needed to be in front of the screen for this to work, you could just look at the screen. but he is showing in the video that he is walking around it more than 90 degrees and it still works, while the phones inside are static
@@OlivioSarikas. The phones are actually not static, they are spinning with the cylinder. (I had edited my first post to clarify this, but it probably didn’t email the update, lol. 🤷♂️)
@@ThetaGraphics ohhhhhh! you are right! because he says in the video it works also with only one phone. thank you
2:41 this doll have a strange feature
Looks great for a DOOM themed Halloween event.
I had a spinning display built 25 years ago. Same principle. Not a new idea. And it was inspired back in the 80's, when I had a toy button on a string with a bird on one side and a cage on the other. What was amazing to me, was not that the bird appeared inside the cage when spun, but that the picture always faced the observer. At the time there was no tech for such displays, but later I was able to do it with a spinning screen and a projector below. The problem with this tech is that it's noisy, unless you're spinning your screen in a vacuum, and with a slit cylinder, you're doing what a privacy screen filter can do way better, without causing you to sacrifice luminance output. The key principle is still the same as in my machine.
Intersting idea about a screen filter instead of a black cylinder, which indeed reduces light ouput.
Came here to post a variant of this. Definitely not a remotely new idea, but having a mass produced refined model of some sort would be a little cool for specific applications, especially public displays
this was drastically simpler than I was expecting. I thought it was going to be something that had to do with projecting an image onto multiple discs of mirrors and then orienting them in a way and spinning them rapidly.
Mike Andos is about to become a very rich person!
So simple but so brilliant. I look forward to seeing products on the market that can do this

@Overcast_Props I started with a cr10 max I got used, it's pretty good but I can see how someone can get soured by the ender 3.
Larger versions could be built with projector screens inside so the electronics don't have to experience high rotational g forces. Have the projectors stationary with spinning mirrors
The projector also has to spin along with everything else. A projected image would be a way to have less/smaller hardware inside the system, however, versus a full-size display.
There's no setup that would keep the image in place as just one part or the other rotated. Hold a hand mirror and spin it to see the effect. There's nothing you can keep in the reflection unless it moves with the mirror, because reflection angle doubles whatever tilt you introduce. Where the phone display blurs the entire image if it's spun without the slit filter, a mirror (including more appropriate silver movie projector screen) would have the image distort, then go completely out of view when it spun, whether there's a slit in front or not.
