OUR NOTEA screen recording of an interactive browser exhibit, 'Pistons vs Magnets', where a four-cylinder engine and an electric motor run side by side, pistons open up at 4,600 RPM, and a magnetic hedgehog demo follows; built in under 15 minutes.

THE CREATOR'S POST

I asked Opus 5.5 again for an engine you can take apart in the browser Pistons against magnets at the same shaft speed. Push the RPM, open the cylinders, slow time down to 1/10 Under 15 minutes, and it did not even move the usage meter on my Max plan. The first experiment took half an hour, this one reused the framework the earlier ones built This is a screen recording, the real thing runs live in your browser Next I want to find where it breaks, so a game is coming

THE PROMPT

Partial prompt — the creator shared only part of it.

Under 15 minutes, and it did not even move the usage meter on my Max plan. The first experiment took half an hour, this one reused the framework the earlier ones built

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.
