Explore the Science of
Visual Perception

Interactive, programmatically rendered optical illusions. Manipulate mathematical parameters in real-time, reveal underlying visual truths, and uncover the neurological mechanisms behind human sight.

Motion

Moiré Interference Grid

When two repetitive, high-frequency line grids or concentric circle patterns are superimposed at a slight angular offset, spatial interference produces mesmerizing large-scale fringe patterns called Moiré bands.

Motion

Rotating Snakes & Peripheral Drift

Created by repeating repeating patterns of asymmetric color bands (Black -> Dark Gray -> White -> Light Gray), this illusion causes stationary figures to rotate uncontrollably when viewed outside direct foveal fixation.
