code_swarm Visualization
The animation below represents the first 6 years of development of the Tux Paint project, compressed down to about 1 and a half minutes. It's visualizes each of the project team members (shown as usernames), and the files they worked on in the source code repository for the core "Tux Paint" application (shown as colored dots — different colors represent different parts of the project, i.e., documentation, data files, and various parts of the source code).
It was generated in October 2008 using code_swarm.
