Rain on a Paris attic window, fog pouring through the Golden Gate, a jacaranda over Sydney Harbour: each of 16 cities is a 480×270 pixel scene that loops every four minutes, with its own weather and street sounds, while new lofi tracks are composed on the fly in your browser. “Follow the night” keeps you in whichever city is closest to 1 a.m., and you can dial the band down to chords only.
