Optical Illusion Spiral Pattern - Visual Perception Experiment #1302445 (License: Personal Use)

This image features a grid of concentric spirals in alternating blue, yellow, and black segments, designed to induce a strong motion aftereffect illusion. Tiny red arrow markers at the edges subtly enhance the perceived rotational movement when viewed peripherally or while scanning across the image. The pattern exploits peripheral drift and neural adaptation mechanisms in human vision.

Used in psychology articles, neuroscience explainers, UX design discussions on visual perception, and educational content about optical illusions; targets users seeking visual demonstrations of cognitive biases or perceptual phenomena.
