They say seeing is believing. But visual perception can't always be trusted. The proof is in this ready-to-color gallery of "impossible" designs created to dazzle the eyes and the mind. Spirals, cubes, rectangles, and other shapes trick the eye and form images that contradict what we know to be true. Yet the results are spectacular! Some of these images seem to move, others become three-dimensional, and all 16 pages are a pleasure to color. Once they're completed, you can place them near a light source for the glowing effects of stained glass.
