Remember the green photo I posted a while back? Or the iceberg? Both photos were from the Opera House. Here is a photo of the Opera House's wave wall. This is what, Snøhetta, the architects say about it: The wave wall: Opera and ballet are young art forms in Norway. These art forms evolve in an international setting. The Bjørvika peninsula is part of a harbour city, which is historically the meeting point with the rest of the world. The dividing line between the ground "here" and the water "there" is both a real and symbolic threshold. This threshold is realised as a large wall on the line of the meeting between land and sea, Norway and the world, art and everyday life. This is the threshold where the public meet the art.
