It's time to stretch your mental muscles
This book provides a welcome departure from the more traditional coloring books available today. But beware, the designs herein may boggle your mind, and confound your eyes; they are all visual illusions.
Combining innovative paper engineering, off-the-page fun and the use of smartphone cameras, this accessible introduction also gives an insight into the neuroscience behind how our brains and our eyes interact.
