I am in a SciPy talk about this library BigBang
https://github.com/sbenthall/bigbang. You can create some neat
visualizations about various aspects of open source communities, like
the mailing list or the git history. Might be interesting for someone
to see what they can do with SymPy.
(and no, the video is not up yet; I am writing this email *during* the talk)
