I would be just like Harry Potter, when it would be possible to print moving photos on a paper or a wall. With a sound preferably. I liked the idea of an moving image of Harry Potter repeatedly saying "Eat dung, Umbridge". Wouldn't it great to paint a graffiti saying obscene things to a passers-by? Then you could hide behind bushes and record a video how people react. Oh, and you could draw another graffiti which might answer to the first one. The city would become a different place, I'd stop using internet and start using reality again. It would be so much fun. Not for a long I expect, then morally wounded citizens would ban moving graffiti to make world boring again. But for a few years we could have a lot of fun. And then move to underground.
