Grayline, the radio that tunes the world
Grayline is a proposed internet clock radio that spins through distant stations while showing their location, local weather, and the moving day-night line.
Why it surfaced

Its ESP32-S3 hardware, station lock, offline alarm, country filtering, and deliberately quiet interface give the idea unusual mechanical and editorial focus.
