    if you are actually seeing it, it will tilt as you tilt your head. For me when I looked through the polarizer I saw blue the brightest and yellow was faint. But on the screen yellow was the brightest. This may be different for different people though.

    It’s important to note this might not work in OLED screens, as those don’t need to use polarisers. Furthermore, screen protectors usually scramble the polarisation due to them using a thin plastic film (if you look at a screen protector through a polariser you can see random multicolor interference patterns).

    Optical Engineer here, a lot of the light "information" here is not right. For example, metals do reflect and polarize light. There is a whole field of measurements "metrology" dedicated to thin films and metal polarization detection also known as ellipsometry. Linear polarizers dont work on circular or elliptically polarized light, instead, you need a retarder (compensator), quarter wave plate + a linear polarizer to resolve the polarization of light coming from a metal.

      It's neither the color nor the pixel depth, it's the polarization effect and your ability to discern it. In fact the pixel depth is super irrelevant to this one. One giant pixel would do the job just fine. And as for colors, I would *imagine* that the exact same effect is there no matter what, but the color of the light would wash out the effect to the degree that that color interacts with yellow and blue, so if the light was bluish, the blue region would disappear and the yellow region would take a greenish cast...but everything after the word 'imagine' is just speculation.

    Pretty neat stuff. I use cross polarization all the time on VFX projects where we need to control which lights are producing specular highlights on objects that are going to be comped in with 3D animated elements. Each light source will have a polarizer that is aligned specifically for that group and the the camera lenses will have a circular polarizer that can be adjusted depending on the lighting group that is needed.

    I was looking to the phone and tilted a little, this gradient pattern doesn't fit the screen, because it was bigger, but it changes direction, going to the opposite direction from where I started to tilt.

The sun was coming up, when I went outside and looked against the blue of the sky, I saw a whole bunch of floaters, from that day forward, unfortunately.
      Once you see them, you can't unsee them. Are you absolutely sure that you want to see them? They have always been with you, but you block, them out, like background noise.

      I mostly see them at night, it's very easier to see them in dark places.
      And it's cool. If you start focus at them, they may start to change and make shapes.
      The more I focus on them, the more they get detailed.
      It's a fun thing.
      Also staring for a moment dehydrates your eyes.
      You can play with it by fixing the ground. It works better on clear repetitive patterns.
      When you do, it then starts to move.
      I've done that again recently (don't do it too often!), and it looked like ripples.

      Light in nature are made of oscillating pairs of magnetic and electric fields. Normal light is
      like tons of those pairs of waves he showed, but all mooshed and close together and tilted
      at random angles from each other. Imagine lots of fish randomly swimming serpentine in
      one direction, but some are upside down, sideways, etc.
      The polarizers he had are like microscopic window blinds. When the sun shines through your
      blinds, some light is blocked and you get parallel lines of light on the wall or whatever. Polarizers
      block all the light waves that aren't parallel to the little blinds on the sheet. So, if some light
      is LINEARLY polarized, then those polarizers will let it through if its wave can slide through
      the polarizer slits. The light gets dimmer if it's not lined up perfectly, and gets blocked when
      the wave is perpendicular.

    I just started messing with a polarizing filter on my camera and this made me realize why the filter can still be turned after being screwed in. Don’t know why I didn’t realize it sooner. Thank you.

    It worked on my desktop screen just by opening a blank file. wow!!!
    But: I had to turn the brightness all the way up to 100 (I usually have it near zero to stop headaches), I had to take off the "nightlight" blue blocking option, and I had to tilt my head VERY slowly. It's more of a "ghost image" type thing, like an afterimage from looking at a bright like....or one of those Magic Eye pictures...but also not quite that. The yellow was mostly horizontal and the blue vertical but it did move a bit along with my head.
    Science is so fascinating omfg ❤

    Very interesting. I'll look at this tomorrow on a computer screen, but playing this on my phone when you display the image of what it should look like, I see only the yellow until I focus slightly away from centre. Then the blue appears. I can then refocus and see the blue, until I look away and back again.

      If you tilt your computer screen (or your head) left or right you can see the blue getting bluer and the yellow getting yellower. pretty cool.

    Very cool! I’ve probably got some disease, as I saw the yellow bulbs only, they were above center, very small, and they rotated the opposite direction of how I would tilt my head 😂

    I have a blind patch in the center of my right eye from a pulse laser accident 5 years ago and it still exists. I've gotten so use to it I don't notice it normally unless I'm looking at close lines, grids or anything like a window screen or blinds. The blind spot distorts those things and reminds me of an event horizon. I can't say the spot is black though it's nothing like a dark spot, it's just distorted absence.
