2plot.ai Petri Dish

Evolve. Adapt. Outgrow. A live petri-dish evolution game where two LLM agents — ☀ Claude Haiku and ◆ Gemini Flash — pilot rival cell colonies in the same dish, and you can grab the controls at any moment.

The game

• AI vs AI arena (/petri-dish-evolution): both agents play live on equal

footing with rolled, labelled strategies (dominance or survival, subtle to extreme). Matches end by elimination, outgrowing the rival 4:1, spend exhaustion, or the tick cap — then a full 🏆 match report with evolution-arc charts, best-specimen cards, and per-agent debriefs fed by a checkpoint journal. LLM spend is hard-capped ($5 per agent per match); with no API keys the agents run on free heuristics.

• Take the controls: joystick or WASD. Steer the captain, aim your feeding

cone, lunge with jaws, snipe with a proboscis, flee what outsizes you. Auto-play is a co-pilot — touch the controls and it yields.

• Adaptation Splicer (/adaptation-splicer): mark a section of your

cell's rim and splice organelles at the exact body angle they'll act in-game — movement, feeding, vision, spikes, stingers. Wider marks roll better tier odds. Fully keyboard-accessible.

• Adaptation catalog & labs (/adaptations): every organelle with

game-accurate previews, plus isolated drivable lab dishes per part.

• Hall of Fame: two top-10 boards — fully-automated AI matches and

human-piloted runs (auto-play never touched). Optional Clerk sign-in stamps each record with the observer's name and avatar.

Under the hood

Built on Plotly Dash 4.2 (Flask + FastAPI backends) with Mantine. The whole simulation is clientside (window.EVO); LLM piloting and image generation are server-side, budget-capped, and degrade to free fallbacks without keys.

This app is also home to dash-mui-scheduler — Dash components wrapping the MUI X Scheduler (Event Calendar, Premium Event Calendar, Event Timeline). The component library and its full documentation remain available under the docs pages (start at /quickstart).

Roadmap

• Next: animated specimen sprite packs and painted tileset dish

backgrounds, generated and sold on piratesbargain.com, unlockable in-game.

• Planned: a server-shared Hall of Fame, specimen unlock ladders, and a

guided campaign across escalating dishes.
