"Open this wordless book and zoom from a farm to a ship to a city street to a desert island. But if you think you know where you are, guess again. For nothing is ever as it seems in Istvan Banyai's sleek, mysterious landscapes of pictures within pictures, which will tease and delight readers of all ages."This book has the fascinating appeal of such works of visual trickery as the Waldo and Magic Eye books". -- Kirkus Reviews"Ingenious". -- The Horn Book

There is also ReZoom, if you didn't get enough Zoom.
