A short two minute code swarm movie showing CVS activity in the VTK respository since January 5, 1994.

The names are those of developers that made commits to the repository, their name fades out as the time since their last commit increases. Files swarm around the developers as they commit changes to them, gravitating towards the developers that last committed changes to those files (dots). The histogram along the bottom shows the number of files in each category that were changed on a given day.
