Three Particles
About
Cullen Webber's piece for The Start's Lab is a colour explosion rendered as a Three.js particle system, magenta, pink, yellow, cyan, breathing over a faint mirror plane with the wordmark "NEVER STOP STARTING™" deadpan at the center. The interesting part lives under the hood. The simulation runs on GPUComputationRenderer (particle positions and velocities solved per-frame on the GPU instead of the CPU), with custom depth shaders feeding a post-processing pass that gives the form its soft motion smear, the bit that makes the mass read as one object instead of a thousand dots.
