Some great photos (via Arch Daily) of Herzog & de Meuron's Olympic stadium, the Bird's Nest. To generalize broadly, architects (including me) love the interstitial spaces of buildings. This is a great example of using this space in between -- not outside, not inside -- and making it alive and animated. The more I see of this building the more I like it. (previously) And, of course, I love the view of the Water Cube!
