Mercurial
A rather different approach to version control. Have a look at http://www.selenic.com/mercurial/. If you know me it will not surprise you that it is written in Python ;).
If you use mercurial and need free hosting on the net, try http://freehg.org/.
All my public repositories are available at: http://trash-media.de/hg/. Do not be scared by the git looks, it is far simpler!
