First you see one thing, then another. The picture changes from one moment to the next, flipflopping back and forth. That's an ambiguous illusion, and the ones in this largestever collection offer constant, pleasurable surprises. Sometimes, the perceptual shift occurs if you just stare at the visual puzzle long enough; in other cases, it's necessary to invert or rotate the image first. In one picture, it's a catandmouse game as you try to discover where the mouse is hiding from the cat. Another image features two minstrels playing homage to William Shakespearebut at first, only the familiar portrait of the bard may be apparent. Once the dual nature of the illusion reveals itself, you'll never see just one object again.
