Optical illusions

About this app

A card deck with five classic optical illusions (Adelson checkerboard, Müller-Lyer, Ebbinghaus, Café Wall, simultaneous contrast) — each card with a precisely constructed SVG illusion and an animated proof button that makes the illusion collapse. A didactic entry into computer vision: perception is construction.
