Simulate a chaotic double pendulum on a canvas using the correct equations of motion, drawing the arms and a colorful fading trail of the tip.
I'll create a standalone HTML file that simulates a chaotic double pendulum with a colorful fading trail of the tip. This will use the correct equations of motion and render everything on a canvas.

I've created a standalone HTML file that simulates a chaotic double pendulum with the correct equations of motion. The simulation includes: 1. Realistic physics using the Lagrangian equations for double pendulum motion 2. A colorful fading trail of the tip that persists as the pendulum moves 3. Interactive controls to reset the simulation and toggle the trail 4. Responsive canvas that adjusts to window size 5. Visual elements including arms of different colors, bobs, and a pivot point The simulation accurately models the chaotic behavior of a double pendulum, where small changes in initial conditions lead to vastly different outcomes. The trail uses a gradient of colors (hsl) to create a visually appealing effect that fades over time. You can open this HTML file in any modern browser to see the simulation in action.
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 with fading colorful trail animates continuously but overlaid ghost trails make it look messy and washed out.

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.
