"The installation tackles questions of control, surveillance, transparency, permanence and the role of the public. A high wall in the shape of a pentagon is erected on Vaterlandtorget square. It consists of a wooden frame with the sides covered in a material that will disintegrate during the course of the exhibition. Initially the wall is smooth, while the weather and the interactions of birds and passer-bys transform it over time. Writing on and penetration of the wall is encouraged." oslo.urban-interface.net
