What it is

3D Life Sim is a browser-based artificial life system where hundreds of thousands of particles form swarms, filaments, shells, lattices, and strange little creatures.

Aaron Lemke has open sourced the project, which turns a WebGPU-powered artificial life simulation into something you can steer with cockpit sliders, live audio, and MIDI mappings. The README describes hundreds of thousands of particles responding to a configurable local field, creating swarms, filaments, shells, and emergent structures.
