This code will create a canvas and draw a double pendulum on it. The pendulum's arms and tip are drawn, and a colorful fading trail of the tip is also displayed. The equations of motion for the double pendulum are used to update the positions and velocities of the pendulum's arms. The `draw` function is called repeatedly to update the canvas and display the pendulum's motion.
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
A red double pendulum swings on its own, but trail is single-color, thin, and lacks a second arm/bob visible.
Vision grade · anthropic/claude-sonnet-5
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.
