During my research on libraries for visualization of large bodies of source code I came over two interesting projects. These projects focus on visualization of whole repositories and results seems more like an art than just pure technical thing…
code_swarm
code_swarm is “organic software visualization of project repositories” for SVN, CVS, Git and other VCS. Examples for different open source projects can be found here.

gource
gource is “software version control visualization tool” for SVN, CVS, Git and Mercurial. Videos with interesting examples can be found here.
