The journey is about two minutes, then it starts over from the beginning.

The program has an interesting lineage. I originally had Claude write it in TypeScript, and that involved all the creative work on my part. Then I had Claude port it to Zig. Then I had Claude port it to Codex, which is an experimental language written by Damian Tedrow. (The name "codex" is not related to the LLM.) Then I had Claude write a Rust program to automatically translate the codex to Roc.
So this is code-generated Roc from agent-written code that was already twice ported. :)
Steve Howell (Sep 11 2026 at 22:03):It's not entirely Roc. It's always had a very thin JS layer to serve up the wasm (whether from zig or codex or roc): https://github.com/showell/roc-apps/blob/master/safari/web/blitter.js
Right now it's only served up on the web. My zig version produces an actual screensaver in Windows. So, the next step is to figure out how to make a Windows screensaver platform in Roc.

Steve Howell (Sep 15 2026 at 17:05):This is now live at https://roc.lynrummy.com/safari/
This project was very pleasant in Roc. It was code-generated from another functional language called Codex , from the Cobblestone project.
Steve Howell (Sep 15 2026 at 20:55):@Luke Boswell There's also a roc-ray version of my screensaver:
For the post:
