Optical Illusion Lab

Generate dynamic illusions inspired by classics like the Café Wall and rotating square patterns. Adjust colours, cell sizes, animation speed, and intensity to fine-tune the effect.

Exploration tips

Try the café wall effect with smaller cell size (30–40px) and high intensity to see the slanted lines emerge.

For rotating squares, combine a pastel palette with slow speed for hypnotic motion.

Increase speed to emphasise motion, then drop to zero to study the static illusion.

Why illusions work

• Café wall illusions exploit alternating high-contrast bands to warp perception.

• Rotating squares trigger rotational motion cues through offset angles.

• Spirograph-like spirals juxtapose radial gradients to hint at depth and twist.

Share & extend

• Pair with the Meme & Sticker Studio to overlay captions on exported snapshots (export support landing soon).

• Fork the tool to add new classic illusions like Ehrenstein or Fraser spiral—Canvas and WebGL are both supported.
