Kevin Ngo had Claude Opus 5 draw every frame of a 27-second animation in JavaScript. The life of a fruit fly, of all things. He also has a set of tiny isometric rooms in the browser (a small light, room by room), drawn the same way. Most of the replies are people asking for the prompt, which is fair.

What gets me is that the output is code. You can read it. Change a number, and the fly moves differently.

So, what I keep thinking about is charts. I’ve built a lot of them from raw data (for the PHP benchmarks, every chart in the report). A benchmark that plays out over time instead of a static bar chart, or a story told one frame at a time, is now a prompt and a script away. I want to try this on the next dataset I get my hands on.
