Song of Github - let me sing you the song of my contributions. (song-of-github.herokuapp.com)

Built while babysitting a migration. Naively approximates the algorithm that generates the contribution graph; I didn't take the time to try to reverse engineer what they're using.

Put your sound up and listen to some frantic piano goodness.

Nice! Should add a 'replay' button or something :)

Edit: Also, the link to Midi.js is borked.
