Dianna Miller, who is finishing up a Masters degree at Ivrea, is looking at how wearables might be used as a means of self-expression, just as clothing expresses the personality and identity of the wearer.
For her thesis, she's developing a "sound accessory" that can be integrated into clothing and controlled by motion or pressure. There's a short interview with her about the project, which is called "Wrapt: sound to suit the wearer". The project site doesn't seem to be available yet.
She's also developed a very cool cape that simulates some of the sensations of flying. I want one! Flightdream.org has demos and a lot of process & implementation details.
