Create a real-time fluid simulation on a full-screen canvas where dragging the mouse pushes swirling colored dye through the fluid.
I'll create a real-time fluid simulation with swirling colored dye that responds to mouse dragging. The simulation will use the Navier-Stokes equations for fluid dynamics and render on a full-screen canvas.

I've created a real-time fluid simulation with swirling colored dye that responds to mouse dragging. The simulation uses the Navier-Stokes equations for fluid dynamics and renders on a full-screen canvas. Key features: - Full-screen canvas with responsive design - Real-time fluid simulation using finite difference methods - Mouse interaction: dragging creates swirling colored dye patterns - Colorful, swirling effects based on density and velocity fields - Smooth animation with requestAnimationFrame The simulation works by: 1. Maintaining grids for velocity (u, v), density (color), and color values 2. Using diffusion, advection, and projection steps to simulate fluid behavior 3. Responding to mouse position by adding forces to the velocity field 4. Rendering colorful particles based on density and color values To use it, simply open the index.html file in a modern browser. Drag your mouse across the screen to create swirling colored patterns in the fluid simulation.

RUN
EVALUATION
Entirely black canvas throughout; JS error breaks color parsing, no fluid simulation renders.

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.
