Hypnotic Smiley Face Optical Illusion - Visual Perception Art #1397520 (License: Personal Use)

A bright yellow emoji-style face with wide, open-mouthed joy and vivid rainbow-gradient eyes sits at the center of layered concentric rings. Each ring alternates bold blue, yellow, and white stripes with black outlines, producing a strong motion-aftereffect illusion when viewed steadily. The gray background enhances contrast, making the spiral pattern pop and intensify the perceived rotation.
