an "organic software visualization" that shows the history of commits in a software project. a "commit" happens when a developer makes changes to the code or documents & transfers them into the central project repository.
both developers and files are represented as moving elements. when a developer commits a file, it lights up & flies towards that developer. files are colored according to their purpose, such as whether they are source code or a document. if files or developers have not been active for a while, they will fade away. A histogram at the bottom keeps a reminder of what has come before.
