Optical Illusion Spirals - Black and White Motion Perception Patterns #3517272 (License: Personal Use)

The image displays four distinct monochrome optical illusions: two radial spirals, one concentric ring pattern with a partial cutout, and a tightly wound spiral with alternating bands. Each exploits luminance contrast and spatial frequency to induce illusory motion or depth. These patterns are widely used in visual perception studies and graphic design to demonstrate how the human visual system interprets ambiguous stimuli.

This image is typically used in educational content about visual perception, psychology articles on optical illusions, design tutorials on contrast and motion effects, or as stock imagery for creative projects exploring mind-bending visuals. It matches user intent seeking examples of motion illusions, teaching aids, or aesthetic vector graphics.
