Wholesale Stoners' Optical Illusions: Trip with Optical Illusions

Are your eyes playing tricks on you, or did you unknowingly (or knowingly) smoke more weed than you thought? This book contains over 150 colorful and mind-bending illustrations, including moving lines, wriggling shapes, and hidden 3D images, all presented in a weedy theme that will make you feel tripped out every time you turn the page. Each optical illusion comes with an explanation of how and why it makes your head spin, demystifying the science into basic concepts that even stoners can comprehend. (This book may contain a sharpie mark on the top or bottom edge and may show mild signs of shelfwear.)
