Mind Games

The following is from a collection of intriguing perceptual illusions featured in Scientific American. These play with our heads and our eyes - and why a particular illusion fools us may not even be known, depending on the example.
Look at the picture below, created by vision scientist Edward H. Adelson of the Massachusetts Institute of Technology. Believe it or not, squares A and B are the same shade of gray.
Scientific American says, "If you don’t believe it, print out this page, cut out the two squares and place them side by side. Our brain does not perceive the true brightness and color of each square but instead determines the brightness and color of A and B by comparison with the squares surrounding them".
Maybe everything really is relative...

See more of these at Scientific American.

The Illusions of Love was my favorite (7 of 11). I'm thinking, "What dolphins?", then I spotted them. ;-)
