I was recently asked to work on a project for Facebook's f8 Developer Conference event (http://www.new.facebook.com/f8/). They were interested in a music visualizer that will be played throughout the 12 hour event and the Hackathon lounge area.

In addition to the visualizer, the programing displays a live text feed of the event where people to post short messages via web (http://www.f8feed.com) / iphone / sms. It's sort of like the event's live Facebook "wall".

The program uses the Toxi / Vec3D library (ttp://code.google.com/p/toxiclibs/downloads/list) for OpenGL rendering. The visual of the program is mostly vector for performance's sake since f8 Feed had to run to the live DJ input off a Macbook Pro.
For the audio, I used the Minim audio library (http://code.compartmental.net/tools/minim) for audio sampling and beat detection. All the feed data is pulled in via XML from the database.
