interesting way of using small displays (Score 1)

This is a rather interesting approach for displaying information on tiny displays. I would love to see something which is connected to a device which triggers the position of one's hand, so moving a hand would move the "underlying' desktop. just like in acrobat, but used in real live. what do you think of this? But by the way, it is nice to see, that there are some peoples out there thinking about new solutions off the beaten track!
