Based on the visuals of the iconic, 1972 map of the NYC subway designed by Massimo Vignelli, Alexander Chen’s Conductor turns the NYC subway system into an interactive string instrument. The application was built using HTML5/Javascript, and pulls in data about the scheduled stops and departure times from the MTA’s public API.
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.
