A film by @StefanoStraus

@StefanoStraus·Sep 28, 2026·Claude Opus 5.5

From the creator's post474 chars

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 creator didn't publish the prompt, so this is what they wrote alongside the film.
