Gource
Software version control visualization
...Gource includes built-in log generation support for Git, Mercurial, Bazaar and SVN. Gource can also parse logs produced by several third party tools for CVS repositories. Gource is a visualization tool for source control repositories. The repository is displayed as a tree where the root of the repository is the centre, directories are branches and files are leaves. Contributors to the source code appear and disappear as they contribute to specific files and directories. Gource's display is rendered using OpenGL and requires a 3D accelerated video card to run.
