Mathematical vision scientists Hitoshi Arai and Shinobu Arai created this unique wreath image in 2011.  If you focus your eyes on the red dot in the center of the wreath and move your head toward your monitor and then away from it repeatedly, you will notice that outer portion of the wreath appears to move to the left and right.

This illusion is a derivative of the Pinna Illusion previously discovered by Dr. Baingio Pinna.
