There's something really magical about a stereogram; in fact, these stunning designs practically come alive with movement. As they tease and surprise our brains, they teach us to look at things differently and make us aware of how our eyes play tricks on us. And, of course, they are simply beautiful to see. Through the power of illusion and the illustrator's skill, meaningless patterns and hidden objects on a 2-D page take shape and pop out in full, glorious, clearly defined 3-D. Images that were flat gain amazing dimension.
