Hi this is a video showing you about the prediction of future technology will be in cities. If you saw the video of the day made of glass it is a similar version. You will see a woman traveling and arranging the meetings with her mobile, a car on time come to pick her up to the location. The host aware of her coming by his mobile, the mobile is like a piece of a glass, it is clear when you do not use ti and when using it, the other side will not be apparent. You will also see a man sing a computer, the monitor using the same kind of technology.
