Simon Twist

Simon Twist is a visual illusion where a two-dimensional image appears to have a three-dimensional, twisting shape. It tricks the eye into perceiving depth and rotation, making the flat image seem as if it’s twisting or curling in space. This effect is achieved through shading, angles, and lines that create the impression of curvature and motion, even though the image is static. Simon Twist is a clever example of how our brains interpret visual cues to infer three-dimensional forms from flat images.
