The Cave in London

What do you all think of this waterfall that is just under the street?  There is a secret to this hidden waterfall, and that is the fact that it is not real, but rather a very detailed and amazing work of art! 

Edgar Mueller, who was born on the westrn edge of Germany, uses a more simple and graphic language for his art. He paints over large areas of urban public life and gives them a new appearance, thereby challenging the perceptions of passers-by. The observer becomes a part of the new scenery offered. While going after their daily lives, people change the statement of the paintings by just passing through the scene.
