How it was made

The author says Claude Opus 5.5 was given one prompt, wrote a physics simulation and a synth that plays Für Elise, and rendered all 1,904 frames itself. No other tools, frame rate, timing, or cost are stated.

Tools: Claude Opus
Effort: One prompt; the model wrote the code and rendered 1,904 frames itself.

Why it works

The sound is tied to the physics: each note plays on a bounce, so the music follows the on-screen motion.
The post ends with a direct question about which ring would trap the ball, which invites viewers to guess and comment.
