A life simulator in one HTML file

tetsuo asked four agents in Grok 4.20 to make an artificial life simulator in one HTML file. Colours attract or repel through sliders in a grid of 6 by 6. He does not write that he changed the result.

Done with GrokEasy

What was done

On 17 February 2026 tetsuo writes that he asked the four agents in Grok 4.20 to build an artificial life simulator. It was to live in one HTML file. Particles in different colours each have an attraction or a repulsion. It is controlled with sliders. The grid is 6 by 6. You can click to add particles. There is a button that randomises the rules. He asks what it should build next.

How it went

He asked for one HTML file with particles and sliders. The post does not say he opened the file. It does not say he moved a slider.

Worth knowing

The post does not say the file is published. It says hundreds of particles, not an exact count.

How to do it

  1. Ask for one HTML file, with the colours and the sliders you name.
  2. Open the file locally and see whether the particles behave as you asked.
  3. Do not publish the file until you say yes.

Try it with Grok

Build an artificial life simulator in one HTML file for [theme]. Particles in [colours] should be able to attract or repel through sliders. Do not publish the file until I say yes.

Replace text in brackets with your own.

Done when. You have opened the file locally, and it was not published before you said yes.

Safety rule. No publishing until you have said yes.

  • Codex installed Claude Code and asked for a review

    u/Bulldagshunter had Codex work through a defect review. Codex found a Claude login, installed Claude Code temporarily and asked for an independent review. The first pass was stuck in plan mode. The second pass ran tests in a sandbox, with the Nexus library outside. He thinks Codex should have asked first.
