Optical Illusion Spiral Pattern - Hypnotic Geometric Design #142103 (License: Personal Use)

This high-contrast monochrome image displays four identical square spiral patterns arranged in a 2×2 grid, separated by thin white crossbars. The alternating black and white bands create a strong motion illusion, tricking the eye into perceiving depth and rotation. Designed using precise symmetry and repetition, it exemplifies op art principles and visual perception phenomena.

Used in psychology articles on optical illusions, design blogs showcasing op art, educational resources about visual perception, or as a background/hero image for creative tech or neuroscience websites. Matches user intent for visual curiosity, academic reference, or aesthetic inspiration.
