This smart little visualization might be the perfect distraction for long subway rides through the city. Using lines that resemble a New York subway map, complete with departing train times, this HTML5 visualization plays the different train lines like a relaxing, random stringed instrument. As each train line crosses another, the string is plucked, playing a gentle note. The longer lines play lower tones while short lines play higher tones. Viewers can also conduct the music themselves by clicking and dragging their mouse across lines.
