Someone turned an LED light into a live Claude Code status indicator, and so can you

A developer created an open-source project called 'Claude Lamp' that connects a Moonside LED lamp to Claude Code's status via macOS Bluetooth LE. The lamp changes color based on Claude Code's state: white/navy when processing, sunset mango when idle or finished, purple when awaiting user input, and off when the session ends. The project is available on GitHub with a full setup guide.
