Grafitti and trains..(Germany)

This is next level shit. Where graffiti is turned into brilliant ideas.

(English:) Anonymous graffiti artists used paint to turn a train door into a window, and a train window into a double door, including the rubber doorjambs and touch buttons. the whole thing was so realistic, the conductor had to put "door not in use" signs on the window so people wouldn't try to walk through it.
