Hypnotic Spiral Optical Illusion - Visual Perception Phenomenon #177954 (License: Personal Use)

This high-contrast monochrome image features concentric curved bands of black, white, and gray that converge toward a central point, producing a powerful illusion of rotational motion and depth. The precise geometric arrangement exploits peripheral drift and motion aftereffect mechanisms in human vision, making static lines seem to swirl. Widely used in perceptual research and visual arts, it demonstrates how the brain interprets ambiguous stimuli.

Used in psychology articles, neuroscience explainers, design tutorials, and educational content about visual perception; ideal for pages discussing optical illusions, cognitive biases, or Gestalt principles.
