BijanBowen had Claude Opus 5.5 build a guitar shop in three.js where every one of the 300-plus instruments it modelled can be played, and making too much noise flips the game into a beat 'em up. It runs a bit laggy, so a Blender and Godot remake is next.93 saves on X

Thariq, who works on Claude Code at Anthropic, had Claude Opus 5.5 try a series of redesigns of their personal website on a Max subscription, using workflows to iterate and critique each pass. It hit the tone they wanted, so they asked it to make a trailer of all the iterations.1.1K saves on X
