I was surfing around the web looking for crazy stuff and I came upon this optical illusion pinwheel. The image is completely static. It does not move. However, when you look at it the pinwheels spin around at the edges of your vision. If you stop your eyes and look directly at a single point in the image the pinwheels will not move. If you let your eyes roam over the image or if you blink repeatedly the pinwheels spin.

Check out the image for yourself!
