New York subway schedule turned into a beautiful, musical visualization (video)

HTML5, JavaScript and a tiny pinch of Flash. Those are your ingredients for building one of the neatest, simplest websites we've come across in a long time. Conductor, as its maker Alexander Chen dubs it, is a visualization built on New York's publicly available subway schedule API. It shows the progress of the Big Apple's underground carriers throughout the day and garnishes the experience with a delightful musical trick every time two lines cross. You can see it on video after the break or just hit the source link and experience it for yourself.
