Run a Gray-Scott reaction-diffusion simulation on a canvas that grows organic Turing patterns in real time, with the mouse seeding new growth.
I'll create a stunning Gray-Scott reaction-diffusion simulation with organic Turing patterns that respond to mouse interaction. This will be a visually captivating demo with smooth animations and interactive seeding.

Perfect! I've created a stunning Gray-Scott reaction-diffusion simulation that generates organic Turing patterns in real time. The app features: ## Key Features: - **Real-time simulation** with smooth animations running at 60 FPS - **Interactive mouse seeding** - click and drag to add chemical B, creating new growth points - **Dynamic parameter controls** for feed rate, kill rate, and diffusion coefficients - **6 preset patterns** (Coral, Spots, Stripes, Holes, Mitosis, Soliton) that produce different organic structures - **Beautiful color gradient** from deep blue through cyan, purple, pink to white based on chemical concentrations - **Responsive design** with a modern glass-morphism control panel - **Touch support** for mobile devices ## How to Use: 1. Open `index.html` in any modern browser 2. Watch the organic patterns emerge from the center seed 3. Click and drag anywhere on the canvas to seed new growth points 4. Adjust the sliders to change the reaction-diffusion parameters in real time 5. Try different presets to see various pattern formations The simulation runs entirely in the browser with no external dependencies, using a high-performance Float32Array-based implementation with optimized Laplacian calculations.
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.
RUN
EVALUATION
Gray-Scott reaction-diffusion grows coral-like blue patterns from a seed circle, reacting to drag/wheel/keys but idle otherwise.

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.
