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.
This optical Illusion is the creation of Herman J. Verwaal of Exloo, Netherlands. This is an amazing illusion that keeps trying to extend beyond its boundries.
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 third (here is the first and the second) of many. I love the constantly expanding image. His illusions run the gambit and I will be showing you more of his excellent Trick-Art in the future.
