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.
Done with Grok Bot
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.
Worth knowing
This is a setup-you-run-yourself option rather than a hosted service, so budget time for installation and upkeep.
Try it yourself with Grok Bot
Build an artificial life simulator in a single HTML file with glowing particles of [number] types, sliders for the forces between them, and emergent behaviors like clustering and orbiting. Test it in a browser and fix any performance problems. Stop when the sliders produce visibly different behaviors and the file opens with no setup.
