Warning: This page contains some works of "anomalous motion illusion", which might make sensitive observers dizzy or sick. Should you feel dizzy, leave this page immediately.This illusion was created by my friend, Herman Verwaal of Exloo, Netherland. Herman took up the creation of optical illusions and pop art after he retired. Unfortunately Herman's time on this planet ended last December. He will be missed but not forgotten. Long ago he gave me access to a large library of illusions that he had created he also gave me permission to display them on my blogs. Here is the second that I have featured on this blog.
This is and example of an anomalous motion optical illusion. Also referred to as peripheral drift optical illusion. As your eyes scan the image the image appears to move. If however you manage to stare at just one point, without moving your eyes, all motion will stop.
That is why this is referred to as a peripheral drift illusion. As your eyes drift across the image the motion is seen out of your peripheral vision. A more detailed explanation of this type of illusion can be found here (as a PDF file).
Printer Alert----> If you have access to a color printer this illusion works on paper too! Print it out to amaze your family or friends.
