mini projector fun

I saw one of these in action at the BBC Blue Room that had travelled to Bristol to show people some nice bits of future technology at New Tools New Ways of Working.
It's an Optoma Pico PK 101 DLP mini projector, about the size of a mobile phone, that connects via video input to your device. The one I saw was projecting video from an iPhone, at roughly the same size as a 13" monitor. It says it can display up to 60". I have a vision of football matches being projected onto all available surfaces at family events. Needless to say I wanted one.
