Optical Illusions

Bats and birds that look like faces. Skulls that pop up on anything white. Three donkeys with three ears be-tween them. And walls that disappear. Relax, theyre only optical illusions. Examine thousand-year-old drawings, find out about closure, perspective, the Rubin vase and how these tools can untangle the tricks found in this volume. A fascinating, visually arresting title, which will keep the kids quiet for hours.
