A cream-coloured orb breathes on this palm-sized retro-Mac screen while your AI agent is thinking, then flips glacier-blue mid-generation and green when it is done — mirroring session state over MQTT rather than any of your text. It carries six daily micro-breaks too, but the full-screen nudge only fires when the plugin sends a time estimate, which today means one harness out of six. ESP8266, GPL-3.0 firmware, $59 assembled.
