Out-of-sight Optical Illusions

by J. Timothy Unruh, The Diagram Group

Optical illusions captivate our imaginations and engage us with their mysterious imagery. These confounding conundrums could never exist in the three-dimensional world, so how do they work on two-dimensional pages? Misplaced perspective; depth inversions; misleading visual clues; discontinuity of planes; ambiguous coverings, shadings, and joinings; altered vanishing points; and other incredible tricks of the trade are all found on these pages. You'll even learn how to create impossible objects in this thoroughly entertaining book. There's only one thing you can count on when it comes to Out-of-Sight Optical Illusions—what you see will never be what you get.
