Something I came across recently and thought was really neat is an app called CodeSwarm. In a nutshell, it shows the history of commits in a software project, day by day and as cool organic images.
Here’s an example of what it produces:
This is a snapshot in time of the Eclipse project.
I was originally alerted to this by Chuck on a sakai-dev posting where some of his students made a video. I decided to make my own and it was refreshingly simple:
svn co http://codeswarm.googlecode.com/svn/trunk/ codeswarmcd codeswarmant run
Enter the repository URL, a few seconds later it’s done and playing onscreen. You can also get it to dump out images and then assemble them into a video with a soothing backing track like many others have done.
Try it out!
