Cool optical illusion – Rotating snakes!

Yesterday I came across this cool optical illusion page. Whenever you move your eye, it appears that the circles are rotating. But if you keep your eye steady for sometime you realize that it is just an illusion!

This is called peripheral drift illusion. This is generated by presentation of a sawtooth luminance in the visual periphery.
