To promote the new Activision videogame Blur, the London based company The Viral Factory have set up some stunning pieces of 3D-perspective street art with the help of internationally renowned artists, across a selection of European cities, among those London. Here you have a video showing a timelapse of the creation process for the Gavin Nolan mural. You also can see images and videos of the mural at flickr.

Thanks Vincenzo.
