I saw this on @Todd_Roy earlier today via @DiscoverMag, who wrote "Oh this? Its nothing, just a picture of 2 perfectly round concentric circles that ur brain will refuse to see."
Of course, I had to confirm immediately: See it for yourselfI didn't have any problem seeing two separate circles.

If you "reverse squint", that is, squint your eyes to purposely put it out of focus, you get a nice pair of concentric circles, albeit fuzzy ones.

They look like circles to me except whichever part is in my peripheral vision almost seems to be moving.
