Created `index.html` — a self-contained double pendulum simulator: - **Correct physics**: standard double-pendulum equations of motion integrated with RK4 at 400 substeps/frame for stability. - **Visuals**: canvas with fading hue-cycling trail of the tip, pivot + two bobs, arms drawn on top. - **Controls**: click to randomize initial angles, Space to pause, R to reset. No external resources.
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
Double pendulum simulation animates chaotically with colorful fading trail; enter/space seems to reset it.

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.
