Create a real-time fluid simulation on a full-screen canvas where dragging the mouse pushes swirling colored dye through the fluid.
thinking
**Planning fluid simulation** I need to create an index.html file and check the current working directory. I'm thinking about implementing a visually appealing self-contained fluid simulation, possibly using WebGL for a fullscreen canvas. I want to incorporate mouse drag to inject dye and velocity in real-time. A 2D grid with semi-Lagrangian JS on a canvas should work, maybe a size of 120x80. I’ll craft a fluid simulation with velocity arrays, RGB dye, and pressure iterations. I'll also add minimalist UI elements and handle mouse/touch interactions while ensuring efficient resizing.

Created `/tmp/ws/index.html` — a self-contained full-screen real-time fluid simulation with: - Mouse and touch dragging - Swirling colored dye - Vorticity-enhanced fluid motion - Responsive canvas sizing - No external resources or network requests - Inline CSS and JavaScript only
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
Drag produces blue dye trail in fluid; click adds small pink dot, no idle animation, keyboard input inert.

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.
