There are two ways of seeing things. And sometimes what you think you’re seeing isn’t really there at all. This playing card deck of 55 poker-size cards presents an eye-catching collection of optical illusions that fool the eyes and delight the imagination. Colors, shapes, and appearances transform themselves magically before your eyes. Each card presents a different optical illusion with an explanation of the effect.

Many of the optical illusions are famous and familiar including the MacKay Effect and the Muller-Lyer Illusion.

Designs in the Optical Illusions Playing Card Deck were created by Pentagram, based on the best-selling books Pentamagic (Simon & Schuster) and Phantasmagrams (Random House).
