Show HN: Babeltro – Nine demoscene effects in 13 languages, pixel-identical (babeltro.storagebits.workers.dev)

I was wondering how those classic demoscene effects come out in different languages. It’s interesting to see the required contortions for each language to get there. For example, SQLite has no float32, so it's emulated in SQL. Wasm has no sin(), so the hand-written port builds its own sine table, to name a few. It was built end-to-end by AI agents. Every port is checked pixel by pixel against the C reference by a script in the repo.
