This book is a bold, modern recasting of the age-old nature-nurture debate, informed by revolutionary insights from brain science, artificial intelligence, psychiatry, linguistics, evolutionary biology, child development, ethics, and even cosmology.

A rich assortment of visual mind-bogglers, including "impossible objects" — constructions that look fine on paper but can't possibly exist in reality — as well as pulsating patterns, vanishing spots, pictures that suddenly change into other configurations as you're looking at them, and much more. 60 black-and-white illustrations.

From impossible shapes to three-dimensional sketches and trick art, you won't believe your eyes as you learn to draw optical illusions in graphite and colored pencil. Perfect for beginning artists, The Art of Drawing Optical Illusions begins with a basic introduction to optical illusions and how they work. Jonathan Stephen Harris then guides you step-by-step in creating mind-blowing pencil drawings, starting with basic optical illusions and progressing to more difficult two- and three-dimensional trick art. Perspective and dimension are difficult to capture for both beginning and established artists, but now you can hone those skills in the most unique way possible, while also exercising your mind with these brain-boosting, unbelievable tricks!

Beginning with the evolution of visual perspective, McNaughton reveals how and why illusions work. She offers optical illusions to suggest to readers that the world they perceive is in fact a complex product of their brains, constructed from the sensory data. Illustrations.

"Incredible Visual Illusions is the most comprehensive and amazing collection of optical illusions ever assembled, with almost three hundred different artworks. You will be amazed as some images flash and scintillate before your eyes, while others disappear right in front of you. Size and shape can lose their meaning, you'll see motion where there is no motion and the laws of perspective are turned on their heads! You won't believe your eyes!" --

How 33 ancient, familiar and new optical illusions work, with 150 examples.
