OUR NOTEA physics simulation where a bouncing ball tries to escape twelve concentric rings, each bounce triggering a note of Fur Elise on a synth built from scratch; all 1,904 frames rendered by the model itself.
THE CREATOR'S POST
I gave Claude Opus 5.5 one prompt: "make a video that could go viral."
It wrote a physics sim, built a synth that plays Für Elise one bounce at a time, and rendered all 1,904 frames itself.

- Ask for one self-contained HTML file on a fixed 1920×1080 stage.
- Link this video as the reference for pacing and style.
- Send two or three rounds of specific notes.
- 3 · Render it to MP4
A short piece like this can be screen-recorded, or captured frame by frame for exact timing.

HOW IT WAS MADE
The creator didn't name their tools. Most videos like this are HTML, canvas or SVG animation written by Claude and screen-recorded or rendered to MP4 — how that works.
