I stumbled upon a page a while back and thought I’d share it with you guys.  Some of you may be familiar with these from psychology class etc. or have seen them before elsewhere. For those who haven’t… don’t hurt your eyes 😀

These are Psychology Professor Akiyoshi Kitaoka’s optical illusions and these are just a few.  Now, it’s important to remember that none of these are animated GIFs or anything like that. They’re all optical illusions. Our eyes are tricky fellows.

Circular snakes appear to rotate ‘spontaneously’.

“Rotating turtles”

“Roller bars”

Boggles the mind, don’t they? The eyes at least. And these are just some of the more “basic” illusions. You can find tons more at Akiyoshi Kitaoka’s website
