Some people may react to this anomalous motion optical illusion and if you think you might be one of these people it is important to read the caution at the top of this page prior to proceeding.
I love the motion in this optical illusion. It is definitely one that you should sit down for before viewing. The quadrants can't seem to determine which way they want to go..
Herman has a large collection of optical illusions that he has created over time. He has generously allowed me to feature a few of his pieces here. This is the sixth (check the sitemap for his others) of many. His illusions run the gambit and I will be showing you more of his excellent Trick-Art in the future.
