Just a bunch of blobs

A million autonomous agents wander a 2D field. Each one lays down a faint trail and follows trails it senses ahead. Two generations are competing for territory: the older one fades, the newer one spreads.

Drag your finger or mouse anywhere on the canvas to paint a wall. Walls slow the new generation down and let the old one breathe a little longer. Open Settings to retune sensors, decay rates and aggression.

Runs entirely on your GPU via WebGPU compute shaders — no servers, no tracking, no analytics. Source on GitHub.
