Perfect, the file has been created successfully. Let me verify the file exists and then provide a summary of what was built.

I've created a real-time fluid simulation with swirling colored dye in `/tmp/ws/index.html`. Here's what it features: ## Key Features 1. **Full-screen canvas**: Uses WebGL for hardware-accelerated fluid dynamics 2. **Interactive**: Click and drag to push fluid and add colored dye 3. **Swirling vorticity**: Implements vorticity confinement for realistic swirling motion 4. **Color palette**: Uses a beautiful HSL-based color palette that cycles continuously 5. **Responsive**: Adapts to window resize 6. **Auto-splatting**: Generates random dye splats every 2 seconds when idle ## Technical Implementation - **Grid-based solver**: Uses a stable fluid dynamics algorithm (Stam method) - **Framebuffers**: Implements ping-pong buffers for velocity, pressure, dye, divergence, and curl - **Shaders**: Multiple GLSL shaders for operations like: - Advection (moving fluid properties) - Divergence calculation - Poisson pressure solve - Vorticity confinement - Splatting (adding fluid/color) - Gradient subtraction ## Usage Open the file in a modern web browser with WebGL support. Click and drag anywhere on the screen to interact with the fluid - your mouse movements will create swirling patterns of colored dye that flow naturally through the simulated fluid.

RUN
EVALUATION
Fluid dye simulation reacts vividly to drag/click with colorful swirling trails, though idle blobs are just static and keyboard input barely differs.

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.
