Hypnotic Spiral Optical Illusion - Visual Perception Study #1870081 (License: Personal Use)

This high-contrast monochrome spiral creates a powerful optical illusion, where the alternating black and white bands simulate rotational movement or inward depth, even though the image is static. The effect exploits peripheral vision and neural adaptation, commonly used in perceptual psychology experiments and visual design studies. Its simplicity and potency make it a staple in discussions of visual cognition and Gestalt principles.

Used in educational content on optical illusions, psychology articles, UX/UI design resources about visual perception, and art installations exploring motion perception. Matches user intent for learning about visual tricks, neuroscience basics, or sourcing striking abstract imagery.
