Optic Illusion gathers 72 optical illusions for you to explore. Every one comes with a direct explanation of what your eyes and brain are doing to cause the effect. 33 interactive, 14 animated, and 72 illusions in total to explore. Written for curious humans. WHAT'S INSIDE • Motion: a still image that drifts, dots that turn into a walking person, a spin that refuses to go round • Geometry: the Café Wall, a spiral that turns out to be circles, two lines your ruler disagrees with • Depth: impossible objects, ambiguous corners, and a room that is the wrong shape on purpose • Contrast: Adelson's checker shadow, and grays that will not match no matter how long you stare • Color: afterimages, a gray picture you will see in full color, and a black-and-white disc that spins up colors • Form: edges, surfaces and whole objects that were never drawn • Attention: five demonstrations of what you are not seeing right now MOTION AND FLASHING Some illusions are in motion, and a few have a flashing/strobing effect. These are protected with a warning that names what the effect is before anything plays. Free. No in-app purchases, no ads, no accounts.
