Moi is a "wearable electronic radiant light device", which is a fancy way to say "LED on a wire". I'm tempted to buy one for $25, though I'm more tempted to just make one myself.
Moi is the brainchild of 5050 Ltd, whose work results from a "fusion of design, engineering, social psychology, philosophy, fashion, style and contemporary culture." Their interest in the social implications and applications of technology is evident in their other wearable prototypes: the courtly bag, the loveJacket (which I think I'd prefer sans cricket chirps), and the mbracelet.
