THIS IS NOT THE OFFICIAL git repository, but github has some neat visualizations
 

I have put my git repository (which for now is just a mirror of the OpenFOAM-1.6-ext repository) up on github, but I explain how this is NOT THE OFFICIAL repository at:
https://github.com/i3enhamin/OpenFOAM-1.6-ext/wiki

I mention this in case you are interested in seeing the impact of different developers at:
https://github.com/i3enhamin/OpenFOA.../graphs/impact

Further, one can see the network/branching timeline at:
https://github.com/i3enhamin/OpenFOAM-1.6-ext/network

Cheers Foamers!

There is another mirror at repo.cz. I have done this for people who need the http-protocol for checkout. This is also a mirror and not the offical repository:
