GPU-Side Physics: A Three.js WebGPU Compute Demo

Thousands of instanced bodies tumble and collide, with the entire physics step running on the GPU through WebGPU compute and Three.js TSL. No CPU round trip, no framerate flinch. A clean little workbench from Kevin Levron, built to inspect, tweak, and learn from.

Elimar: A Lost Van Gogh, Rendered in Particles

OddCommon's hour-long scrollytelling for LMI Group renders Vincent van Gogh as a cloud of black and white motes that scatter on approach and reform at distance. One particle system in many disguises, wrapped around four years of forensic art authentication.
