<DIV><DIV>Prepare to be amazed! Inside the covers of this incredible, colorful collection are hundreds of the world&#8217;s most powerful optical illusions. They&#8217;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&#8212;including a mouse playing hide and seek in a cat&#8217;s face and a strange desert mirage where palm trees imperceptibly morph into camels. And still more, like &#8220;The Impossible Terrace,&#8221; which couldn&#8217;t exist off the page: just try to figure out if you&#8217;re viewing the space from above or below. Every one is astonishing.</DIV>
