Hypnotic Spiral Optical Illusion - Visual Perception Study Image #3817414 (License: Personal Use)

This high-contrast monochrome image features tightly wound concentric rings forming a logarithmic spiral that induces a strong motion aftereffect. The alternating black and white bands exploit peripheral vision mechanisms, often causing perceived rotation or inward/outward movement when viewed steadily. It’s widely used in cognitive science, art therapy, and graphic design for its compelling perceptual impact.

Commonly employed in psychology experiments on optical illusions, mindfulness apps for focus exercises, educational content about visual perception, and as a background or decorative element in digital art and UI design where attention-grabbing visuals are needed.
