The New York Subway as Stringed Intrument

This imaginative animated visualization tool uses the the NYC subway's schedule and plan as a stringed instrument. The piece begins in real time by tracking trains scheduled to depart in the last minute, then continues accelerating through a 24 hour loop. The visuals are based on Massimo Vignelli's 1972 diagram.

I love how the line/tone struck is appropriately higher or lower depending on the distance between the nearest two stations. I also love the added touch of the "bounce" animation. Whimsical.

Here is a recording of one start time.

Conceptually, a beautiful metaphor. What might be the useful applications for learning?
