Pandemonium Books put on a play performance of Guards, Guards, the novel by Terry Pratchett (adapted by Stephen Briggs). It was neat. While I was there I discovered that Pandemonium Books may be a cool place to geek out, so I'll probably be visiting again.
Speaking of geeking out, I hear Tenth is moving up to Boston this weekend, and I've heard that he's threatening to run a role-playing game of some sort. Bring it on, I say.
By the way, did you know PyPy can run Twisted-based Internet servers and clients now? Our conviction is like an arrow already in flight.
