When I visited Venice with out a doubt my favourite pavillion was the Venezulan pavillian. It had quite a focus on graffiti, I never knew that graffiti was such a big part of the culture in Venezuela.
I walked in to be greeted by a blank wall, the lights would go down and a projection of a man walked up to the wall. he then started to spray graffiti across the wall and lights picked up the individual sections of the piece. It was very surreal and a great marriage in my mind of the virtual in a real space.
