A week ago I wrote about visualization for dynamic data sets, and described briefly code_swarm a project to display organically the activity of software repositories.
I'm really glad to see that Michael Ogawa has open sourced the project and uploaded it to Google Code. You can access to project at codeswarm.
You can browse the code for the code_swarm prototype or check it out using subversion:
$ svn checkout http://codeswarm.googlecode.com/svn/ \ codeswarm-read-only
I want to play a little bit with it, the visualization for kernel must be amazing. Also it will be curious to see how the interactions changed from the 2.4 to 2.6 with the new versioning policies.
