Motion Illusion Spiral Pattern - Visual Perception Phenomenon #97918 (License: Personal Use)

This striking optical illusion features a grid of concentric spirals in alternating blue, yellow, and black segments that create a powerful perception of rotational motion. Though entirely static, the arrangement exploits peripheral drift and luminance contrast to trick the visual system into seeing movement. Small red arrow markers highlight points of apparent motion initiation.

Used in psychology, neuroscience, and design education to demonstrate visual perception quirks; ideal for articles on optical illusions, cognitive science, or UX/UI design principles.
