Prepare to be amazed! Inside the covers of this incredible, colorful collection are hundreds of the world's most powerful optical illusions. They're beautiful to behold, and stunning in their trickery. Some of the mind-boggling images seem to spring into action, vibrating, pulsing, and spinning like a hula hoop. Other ambiguous illusions feature two subjects in one: the fun is in finding them both in the single picture--including a mouse playing hide and seek in a cat's face and a strange desert mirage where palm trees imperceptibly morph into camels. And still more, like "The Impossible Terrace," which couldn't exist off the page: just try to figure out if you're viewing the space from above or below. Every one is astonishing.

"Seeing is not always believing."
