EVALUATION
Double pendulum with colorful fading trail animates continuously; drag/click/wheel perturb it, space pauses correctly.

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.
