Created a self-contained **Gray-Scott reaction-diffusion simulation** in `index.html`. Open it in a browser to see organic Turing patterns emerge in real time. Use your mouse to seed new growth. **Features:** - Adjustable parameters (feed/kill rates, diffusion constants) - Mouse interaction to add new patterns - Fully self-contained (no external dependencies)

TAKE IT TO CODE

A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

EVALUATION

3/5 working

Gray-Scott simulation animates and evolves patterns on its own; drag seeds visible new growth, but click/wheel/keyboard show no additional effect.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
