Check out this link to flickr images of The Birds Nest - the Olympic Satadium in Beijing by Herzog and DeMeuron. It is a beautiful form and a very expressive skin. In these images you really get a sense of how the architects created a blurring between the inside and outside of the building. You also get a blurred sense of where the building starts and the plaza ends. Even the roof tends to be ambiguous in the way it expresses inside and outside.
