Presents visual puzzles that challenge perception and perspective, including hidden figures and reversing cubes.

Visual illusions are compelling phenomena that draw attention to the brain's capacity to construct our perceptual world. The Compendium is a collection of over 100 chapters on visual illusions, written by the illusion creators or by vision scientists who have investigated mechanisms underlying the phenomena. --

In this book you will observe some very creative ambiguous figurative illusions by Humberto Machado where both aspects share space, and cannot exist without the other. Ambiguous illusions are fascinating because they remind us of the discrepancy and reality. These illusions occur as a result of how information is interpreted in the brain. At the end of the book you will come across some famous optical illusions by some very well-known psychologist and physicist like Ewald Hering and Johann Poggendorff.

These amazing artistic optical illusions have real depth - that's because they're in 3D! Some have to be viewed through a pair of red & blue paper glasses, which come with the book: put them on & watch decorative cubes, towers, & other complex geometric drawings spring to life, gaining volume & space.

25 hand drawn illustrations / illusions to color Each coloring page is printed on a separate sheet to avoid bleed through Each illustration is printed twice (duplicates in the back) for a total of 50 pages.

Why do we need two eyes? Why are all cats grey at night and appear to move faster the day? Why is the sky blue and the setting sun red? This book explains the multifaceted nature of perception, and discusses the mysteries of vision. It provides readers with experiments to help them discover optical illusions and the features of their own perception. Illusions of Seeing begins with a discussion on the essence of light and its perception to the human eye. It presents a comprehensive overview of the basic laws of human perception as well as the fundamentals of good gestalt. Subsequent chapters discuss geometric-optical illusions; the perception of form, brightness, and translucency and their interaction with each other; ambiguous perception, color vision, spatial vision. The book ends with a discussion of the perception of motion and its interaction with color, form, and spatial depth with a full chapter devoted to illusions in our everyday life. Consider this your travel guide in the marvelous world of sight, to experience a completely individual way to understand and improve your own perception. Illusions of Seeing will be of interest to psychologists, physicists, biologists, and undergraduate and graduate students within the field of cognitive psychology.

Gianni Sarcone offers an approachable how-to for graphic designers, teachers, and artists who want to explore illusions that are distorted in size or create the perception of movement. Amateur illusionists are invited to draw curves that diverge and converge, diamonds that vibrate and flicker, hypnotic spirals, ghosts, and ambiguous figures, and many other visual tricks.

Paul Baars presents many fun examples of optical illusions.
