Eye-Popping Optical Illusions

Every image in this follow-up to Optical Illusion Magic is out to trick your perception with afterimages, visual “traps,” and distorted views. Sometimes you’ll have to shift the page to see the magic; in other illusions, pattern and shape make all the difference, producing spirals where none really exist. “A book with a fresh perspective, lots of scientific information, and hours of fun.” —School Library Journal. “Will entertain and educate.”—Booklist.
