I’ve been working on a browser-based evolutionary simulation as a personal experiment.Organisms adapt to environmental pressure over time, and there are no explicit goals or scoring, the system is open-ended and runs continuously.I built this mainly to challenge myself and to explore how to surface simulation behavior and statistics in a way that stays readable rather than overwhelming. As a side effect, it’s also something my kids enjoys watching run.Curious what resonates and what doesn’t, and happy to answer questions about the design or tradeoffs.

Could you build this?
Yes This is a browser-based artificial life / 2D genetic simulation rendered on HTML5 Canvas or WebGL. A solo builder can prompt an LLM to generate the entity physics, genetic mutation rules, and animation loops.
