The Medusa and the Snail

The Medusa and the Snail are visual illusions that demonstrate how our perception of motion can be influenced by pattern and animation. The Medusa appears to have moving, wavy lines that can seem as though it's writhing or twisting, while the Snail uses subtle shading and repetitive shapes to evoke a sense of slow movement. These illusions trick the brain into perceiving motion where none exists, highlighting how visual cues and contrast can manipulate our experience of still images, revealing the fascinating ways our perception interprets information based on pattern, contrast, and context.
