Illusions 17

This is a static image. It is not animated in any way but as your vision moves back and forth the center area seems to be moving toward the center (contracting) and the outer edges seem to be moving away (expanding) from the center.
If you fixate on a point in the center and don't move your eyes this anomalous motion will stop! Funny, isn't it?
