someone asked Opus 5.5 for a train journey in a risograph print style, with every frame drawn in JavaScript, and it made this in one go in about 45 minutes no image model, the visuals are ALL code. and the whole project is public on GitHub (sevenevesai/riso-windowseat), so you can point Claude at it and make your own if you've only ever used Claude for web apps, try asking it for an animation. it's a lot better at it than people expect
