Google engineer Alexander Chen has converted live data from the NYC subway schedule into an online “stringed instrument” called Conductor (above is just a video example).
Conductor turns the New York subway system into an interactive string instrument. Using the MTA’s actual subway schedule, the piece begins in realtime by spawning trains which departed in the last minute, then continues accelerating through a 24 hour loop. The visuals are based on Massimo Vignelli’s 1972 diagram.
