New things: Further adventures in stereographic projection. These are available from my Shapeways shop at www.shapeways.com/shops/henryseg?section=Stereographic+Projection The torch/flashlight is a Mini Maglite LED flashlight (www.maglite.com/aaa_led.asp).
Imagine having three Mini Maglites, each filtered through a bit of colored plastic, each with its own 3-d printed mask. You could get a picture with colors black, red, green, blue, cyan, magenta, yellow, and white.
I was thinking about that. It's hard because you only get those 2^3 colors, and they'll be pretty lurid. Maybe get somebody to draw a parrot (in a computer program, obviously). Alternately, take something well known, so at least it's recognizable, and round its colors to these 8. It can't be something with lots of browns, like the Mona Lisa. Maybe Warhol's Marilyn? artisme.files.wordpress.com/2007/09/marilyn.jpg
Doesn't have to be just RGB. I could imagine working something out with other colours as well. The fall-off of brightness with distance from each light source might be an issue.
If you had a sphere with the continents marked on it - which might be difficult to set up in this medium - you could demonstrate the relationship of this to map projection.
My 1st thought was that would give you Gleasons New Standard Map Of The World, with its Azimuthal projection as displayed in the UN and used by flat-Earth advocates. But it wouldn't.
Put such a sphere in the center of a tall cylinder of tracing-paper, with the light source at the center of the sphere, and that would give you a Mercator Projection. Which is what most maps use. Except that they trim down the poles, which would otherwise appear at infinity.
Another way to see that the centers of the circles are not preserved is that the centers of the inner and outer edges of each ring are not the same. this ia what causes the rings to be thinner near the light and thicker farther from the light.
Not to pick on your work, but you NEED to put a bit more time into embedding a structure to hold your light source. A few supports at regular intervals would be easy enough to add, and some struts on the bottom to keep it from rolling over. A little hood around the light source would keep the light from blinding observers. Once done, it could be very useful for tabletop gaming, as grids (square and hex) are always useful for gaming. If I could see your model, I could do the modifications for you.
Max SMoke For other projects I have made a socket to put the flashlight in, which supports it. The reason I don't do that for these pieces is that adding such a socket makes the print unusable with a light other than this particular flashlight. Lots of people buy or print these for use with their phone flashlights.
I wonder what's your opnion on were do you believe its the position of our sun , ignoring whar's its been said or what is consider as a fact now day, giving this exellent experiment or finding you have encounter, can you share your toughts on this please?
Idk why but I love this guys voice
I want that as a table lamp so bad.

Allen Knutson, Jay Schweig had exactly the same idea - but what should the picture be?

i was thinking Escher tesselations

Yes, I've thought about this. Connectivity is an issue, but I have an idea for how to do it!
@@henryseg I just found out about your channel. Not sure if I'll find it when I'll watch all your stuff. but if not, it's still a cool idea :)

This would make an excellent lamplight

Amazing work!
Very nice!
Thank you!
Thanks For Such Videos
I liked it
simple but Very Nice for understanding
nice art...get my room.
I think the circles dont preserve...
They become ellipses.
and if the endpoint is parallel to the lightsource its a hyperbola

I think this begs to be turned into interior decorative lamp designs.
👍🏼👍🏼
it is nice but I need to do a working model based on this topic that which happens in our real life I need ur help or support please do reply
2:47 Would it be fair to say then that an analogy between a Mandelbrot set and this projection could be drawn?
Well, they are both shapes composed of circles 🍳😶🧿💿☣️♉⭕🔘
hi dear how name you software for make this? tnx, i can you stl file
