FOSCON III was a blast last night. There were lots of talks about subjects as diverse as generating midi and controlling Lego Mindstorms robots with Ruby. Plus, there was the most pizza I've ever seen in one place! Thanks a lot to Thomas Lockney and all the organizers for putting it on.
Here are the slides from my presentation: RAD: Physical Computing with Ruby. I'm planning on supplementing them with some video of the demos as well as a few additional slides to fill in the holes that appear without the audio. Also, I'm working on getting video of the talk from the Box Populi folks who were shooting last night and I'll post that as soon as I've got it.
