Looking like a cross between a Geiger counter and something unpleasantly endoscopic, the SMS Guerrilla Projector is in fact the mash-up of an old Nokia cellphone with a variety of camera lenses; it lets you project your text messages onto anything or anyone.  Designed and constructed by Troikart, a UK-based experimental art and design collaborative, it's intended to provoke thought and discussion based on the interplay of message and backdrop.  Whatever the theory, I want one!
