Weirdest optical illusion I've ever seen.

[Skeptic Ginger]

Yeah, it's just camouflage. By moving the image, you motion-blur the checkers, exposing the image .. for me, looking from distance, thus using out-of-focus blur of my poor eyesight, works even better.

It's not camouflage, it's your brain deciding you are looking at a checkered pattern despite the fact it is a slightly altered pattern. When you move it, it takes your brain a second to revise it back to what it thinks you are looking at.

Neat, although I wouldn't say it's esp amazing.

This is the one that had me shaking my head more: http://www.slate.com/blogs/bad_astronomy/2013/12/07/optical_illusion_shades_of_grey.html

That checkerboard demo was awesome. She even repeats it several times in the video to prove the color. Is the same. I think God is changing it. Miracle, I say! h

I find with a laptop the easiest way to see it is to tilt the screen. At least on mine the screen darkens when tilted, and the coloration of the squares stands out more.

I am very partial to the Einstein/Marylin Munroe illusion - which must have some similar principles involved in terms of visual perception, but is far cleverer.

Yes, but what if she has my high frequencies, and your low frequencies?
