forked from: BeatDrawing + MP3 Choice

Just added loading MP3 from hard drive to see how it visualizes other songs. 
Cool stuff, reminds me of one my own visualizer from here http://wonderwhy-er.deviantart.com/gallery/2601142#/d1j6l06
Will need to get to porting it to WonderFl :)

Update: 
Tuned params a little to allow more quite songs to produce some change
Also removed random colors and made coloring somewhat change with the song
