This is a visualization of the svn commit logs of SuperCollider (a real time audio synthesis programming language supercollider.sourceforge.net/) project. The logs were taken from sourceforge, it starts from July 13, 2004 and ends in November 23, 2008 covering 1594 days (or in other words 4 years, 4 months and 10 days) of activity.
The visualization is made with the great code-swarm project by Michael Ogawa (and probably others). You can obtain it from: vis.cs.ucdavis.edu/~ogawa/codeswarm/
The music piece is taken from one of my own works (which is also created entirely with SuperCollider and deQuencher btw).
SuperCollider is a great environment and I wanted to create this to show my appreciation to those who are making it possible! And... data visualization is fun. Eh... Enjoy. :)
