Europe's biggest graffiti wall

In an effort to bring tram station in demise back to life, the city of Brussels invited 60 graffiti artists from all over Europe to create Europe's biggest graffiti wall (4500 square meters). It took 9 days and 6000 spray paint cans to create this massive piece of urban art. I quite liked this bit with a futuristic comic city image.

Funny fact: the tram station is called "De Wand", which is Dutch for "The Wall". And it was already called that before the graffitit artists came along! :)
