Optical Illusions Storm T-Shirt

Inspired by the Pinna illusion—the pioneering visual trick that first demonstrated the perception of rotational motion—this image plays with our visual perception. At first glance, the swirling pattern of tilted black-and-white squares seems to form a dynamic spiral. But take a closer look, and you'll discover that the squares are not coiling at all. Instead, they trace out four perfectly circular, concentric rings, tricking the mind into seeing motion where there is none.
