Hosting an open air graffiti event in a city like Rotterdam is not an easy task. Graffiti is mainly illegal in Rotterdam, so the artists from the city have very short time to paint, and their art is normally taken as vandalism by the government and general public. It is hard to convince people to give up the virgin enormous sidewalls of theirs houses to a bunch of Brazilian graffiti artists who they have never heard of. Little do they know that these writers did not travel all this way just to put their names on the walls. They came to change the perspective of graffiti art in Rotterdam, and to show how far they can take urban interaction.
Even after getting permission for most of the walls, to decide who was going to paint which wall was a different, but not less difficult, mission. Days went by and now everyone is thinking, creating, sketching and trying to cope with the fact that now they actually have to paint these huge, and I mean gargantuan, walls.
