Chip fab simulation replays 30 days of Claude Code usage

An Xuan built a live 3D chip fab in three.js that turns their last 30 days of Claude Code into a strategy-game-like simulation: 2,656 sessions become wafer lots, 86,131 tool calls become process steps, and errors become bad wafers. Built with Claude Opus 5.5 and viz3d.

Improved my chip fab, and this version runs on real data

It replays my last 30 days of Claude Code, with 2,656 sessions, 86,131 tool calls and 27B tokens. Every session is a wafer lot, every tool call a process step, every error a bad wafer
