6th sense technology. The tourists dream machine.

I just caught this TED video over at code2ave.com and can I just say that I love technology. This is something that I would use, although I would prefer if it were in the form of eyeglasses and a medallion for the projector. The eyeglasses, having a couple different styles and made available in tinted or non and the medallion hopefully with either a piece symbol or the continent of africa for a lens cap. I could also see it being stolen from the MIT kid who invented it and then becoming an app in the app store. AAAAPPPPPPLLLLLLEEEEEE!!!!!!!!!!!!!
