Run a Gray-Scott reaction-diffusion simulation on a canvas that grows organic Turing patterns in real time, with the mouse seeding new growth.
thinking
The user wants a Gray-Scott reaction-diffusion simulation as a single-page web app in index.html. This is a classic Turing pattern simulation where two chemicals U and V react and diffuse, creating organic patterns. The mouse should seed new growth. Let me create a complete, self-contained HTML file with: 1. Canvas for rendering 2. Gray-Scott simulation using GPU (WebGL) or CPU (JavaScript) - I'll use WebGL for performance 3. Mouse interaction to seed patterns 4. Real-time animation I'll write this as a single HTML file with inline CSS and JS.

The file has been created. Let me verify it works by checking the file exists and its content.

thinking
The file is created. The web app is complete with: 1. Gray-Scott reaction-diffusion simulation using WebGL 2 for GPU acceleration 2. Real-time Turing pattern generation 3. Mouse/touch interaction to seed new growth 4. Adjustable parameters (Feed, Kill, Diffusion rates, Speed) 5. 9 classic presets (Mitosis, Coral, Worms, Maze, Spots, Chaos, Fingers, Spirals, Replicators) 6. 7 color palettes (Classic, Ocean, Fire, Neon, Mono, Viridis, Plasma) 7. Reset and palette cycling buttons 8. Responsive design that works on mobile 9. Single self-contained HTML file with inline CSS and JS The implementation uses: - Ping-pong framebuffers for simulation - 9-tap Laplacian for isotropic diffusion - 1D texture for color palette mapping - Full-screen quad rendering This should run smoothly in any modern browser with WebGL 2 support.
Created `/workspace/index.html` — a complete Gray-Scott reaction-diffusion simulation with: - **GPU-accelerated WebGL 2** simulation (512×512 grid, ping-pong framebuffers) - **Real-time Turing patterns** — spots, stripes, worms, chaos, spirals, replicators - **Mouse/touch seeding** — drag to inject V-chemical and grow new structures - **9 classic presets** (Mitosis, Coral, Worms, Maze, Spots, Chaos, Fingers, Spirals, Replicators) - **7 color palettes** (Classic, Ocean, Fire, Neon, Mono, Viridis, Plasma) with cycling button - **Live parameter control** — Feed (F), Kill (k), diffusion rates, simulation speed - **Reset button** to re-seed from center - **Responsive** — works on desktop and mobile Open `index.html` in a browser to run.
