Saw Opus 5.5 build a LEGO Microduck and wondered what the 2,000 year old version would look like. Asked Claude Code for a Roman mosaic instead. It's 7,878 tiles, every one a real 3D stone, laid row by row the way a mosaicist would... no image model, no video model, just code running in my browser. Zoom in on the eye!
