We ran our presentations last night with Impressive, a python presentation framework, rendering directly from PDFs that all the speakers provided. It’s a nice package. I’ll be giving a little demo tomorrow at MichiPUG. I also wrote up a detailed explanation if you’re interested.
Also, the half-time twitter visualizer was visibletweets.com, which I think worked great. We had a lot of twitterizing from the crowd that was thrown up on the screen at half-time.
