Attention Smartphone required

So I luckily a smart phone at home so that I could get started quickly. but had not been described in the sale. Then, however, it's amazing. only download an app and the stunned spectators sitzten gaping and not believe their eyes.
I find this game great. A special film is the mirror image of the cell phone display is used to give the impression there is a real figure, the talk and interact with the real world. the audience sitting in front of the back of the display and can see only the mirror image. but afterwards he can not get that it's just a reflection because the figure with real objects interact. It's difficult to explain but it is very fascinating
