These are very interesting illusions. Most of them work on me especially the one shown here, as long as my eyes keep scanning. You can stop them by concentrating on one point. Some of them don't work or don't work as well on me. Pretty hard to trust your eyes when they fool you like this. Anyone out there red-green color blind? Do these illusions work on you? What ones did you like or dislike? Could you paint your car with one of these patterns? He was moving really fast, officer. Would that be dangerous? Wonder if natural selection has ever produced such a pattern in the biological world?
