with 29 new mind-bending 3D illusions. 2D illustrations will magically
morph before your eyes to reveal what is secretly hidden in 3D. The
images will not simply appear to be 3D, they will become 3D! Viewing
instructions and a solution key are included. The longer you look, the
clearer the hidden 3D image will become. The further away you hold the
page, the deeper it becomes!
