#32Earlier quoted context omitted.
I'm still not convinced. They said the answer is pink. But...it wasn't pink, even to their own admission. A pink shoe, when placed under pure-green lighting is no longer pink: at this point we're out of illusion territory and into lighting trick / semantics territory. If they'd have said the answer is green-gray, then fine, this would be an illusion for those people who incorrectly thought the shoes are pink, but the…
The picture is gray, but the actual shoes are pink, but bathed in green light. Some people sometimes can mentally remove the green lighting.
This is what I don't understand. I thought the socks were green, not white in green light, and still thought the shoes were pink.

#33Ah, the “phantom wiggle”: I’ve witnessed this so often in my rear view mirror from certain vehicles (usually vans). I thought I was going mad, but now I know! I didn’t realise LED lights strobe.

#34Very cool. I looked back at the 2020 finalists, and the first video from that list truly boggled me: https://youtu.be/5DYeAkx2IBo. At around 16s in, my vision of the stair case suddenly and completely changes to being upside-down to rightside-up. I know what's going on physically, but it feels like my brain is doing these behind-the-scene calculations and at a certain moment feeds my conscious mind a brand new image. Pretty neat how some optical illusions can put you at odds with your own brain.
quick edit: It doesn't always happen for me when I let the video continue to play, but if I pause it at 16s, then as soon as I hit the pause button, the image completely flips for me. Pretty wild. I think it's probably because I let my eyes drift away from the staircase for a brief moment, and when they return the image is sort of reinterpreted.

#35The crocs illusion is just plain wrong. It says "the correct answer is ". They then contradict themselves by saying it's green-gray. It's green-gray. Am I crazy? Any else's thoughts?
I wasn't too impressed with this one, either. In my mind, this illusion is much more straightforward demo of a similar effect (color perception being relative to surrounding colors): https://www.illusionsindex.org/ir/checkershadow
The shoe example seems closer to a weaker version of this effect:

#36Majority of the illusions seem to be 2D object projected as 3D object, they still get me every-time though. Definitely would recommend a game called Superliminal if this kind of stuff gets you.
And if you like Superliminal you would definitely like Antichamber.

It's also interesting how with most visual illusions, you can sort of convince your mind to interpret it one way or another if you try hard enough. I think the simplest example is the necker cube, where you can convince your brain it's either pointing towards you to the left or towards you to to the right [1], seemingly just by visualizing those orientations. In case I'm not the only one who interprets it this way, I'm wondering, is there a name or academic description for that phenomena?
The wikipedia article mentions:
> There is evidence that by focusing on different parts of the figure, one can force a more stable perception of the cube.
Which is pretty interesting by itself, but I think it implies the need to physically move your eyes. What I'm curious about is the ability to alter your perception without moving your eyes physically. It seems like evidence for or against that could lead to some interesting conclusions.

#38The second place should really be the winner. It’s absolutely astounding!
Re: Illusion of the Year 2021
#39Some of these are pretty cool but I always feel like the ones that depend on the camera being in a fixed perspective aren't nearly as cool.
I agree, with a fixed perspective you can show anything you want.

#40In "the double ring illusion" I'm unable to see them as 180° rotations. I see all rings in the video doing constant 360° rotations, and I don't care if they intersect. Maybe I'm too used to see virtual 3D animations where objects can intersect and do whatever they want without any physics involved.
Yeah, same. Maybe we've learned too much to expect stuff to go through other stuff from 3D graphics, but that seems a bit dubious. It's probably just not as reliable as the authors say.
