The presentations I remember most from the last day where "Sonification of Facial Actions for Musical Expression" and "Pocket Gamelan: a Pure Data interface for java phones".
The first one was about a way of recognizing facial expressions to generate music.
The second one was a Pure Data to J2ME converter. A program that could translate PD patches to MIDlets (Java programs for mobile phones).
The rest of the day is blurry... :)
