Opus 5.5 creates a train journey drawn entirely in JavaScript

Opus 5.5 has an obvious step up in riso art and animations I noticed. It single-shot this in about \~45 minutes. Full claude repo here - have your claude pull this into a new project folder and happy days: [https://github.com/sevenevesai/riso-windowseat](https://github.com/sevenevesai/riso-windowseat) The piano recordings for the music/score's notes are [Salamander Grand Piano V3 by Alexander Holm](https://github.com/sfzinstruments/SalamanderGrandPiano). Recommend having claude find better open source instrument sound recordings (such as this) to slap on top of the scores it writes, makes a huge difference.
