MTA.me

A clever project that "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." Built with HTML5 and JavaScript. See it in action here and read the project summary here.
