You know, what you see is not necessarily what you get. That's because vision occurs in the brain, not in the eyes. The eyes serve only as a conduit for visual information to reach the brain, which then interprets the data. And believe me when I tell you that our brains can play some amazing tricks on us, as you'll appreciate by exploring these puzzles.
For most of you, you'll do best to leave all of your preconceived notions about vision at the door, and just enjoy your time here. For those of you who are not satisfied with simply being amused and who want to delve more into the ins and outs of optical illusions, along with their technical explanations, visit Michael Bach's Visual Phenomena page. It is one of the most interesting web sites I’ve seen on the subject. So relax and have fun!
