Hypnotic Spiral Optical Illusion - Visual Perception Phenomenon #142075 (License: Personal Use)

This image features a repeating geometric pattern of interlocking spirals in blue, yellow, and gray, designed to induce a strong illusory motion effect. When viewed peripherally or while moving your eyes across the image, the static spirals appear to rotate continuously due to the brain’s interpretation of contrast and orientation cues. It’s a well-known example of a peripheral drift illusion, often used in vision science and cognitive psychology demonstrations.

Used in educational articles on visual perception, neuroscience blogs, psychology course materials, and design resources illustrating Gestalt principles; targets users searching for “optical illusion examples,” “how do illusions work,” or “motion aftereffect.”
