Build an artificial life simulator in one HTML file

Four Grok agents were asked to build an artificial life simulator with glowing particles, force sliders, and emergent behaviors.

What they did

Four Grok 4.20 (Beta) agents received the prompt to create one self-contained HTML file simulating hundreds of glowing neon particles across six cyberpunk colors, with a 6x6 matrix of attraction/repulsion sliders, click-to-spawn controls, randomize button, pause/speed/particle-count toggles, and optional trails plus dark UI effects. The agents generated the full file independently. The user opened it and recorded the running simulation.

How it went

The file produced swarms, orbiting rings, chasing packs and exploding clusters that the poster called mind-blowing; a short video of the live demo was shared.
