I've just uploaded the source for goblet, my git web interface project to github. It's not quite complete yet, but I already find myself using it more than github's own web interface as it has fewer distracting elements. Current TODO list includes a working search, a blame view and fixing the branch selector, which looks odd in Chrome.
If you feel like using it, the README document should help, though it helps if you're a bit familiar with python, pip (and possibly virtualenv). Another item on the TODO list is packaging goblet and all its dependencies and sticking it in a PPA.
