plant cities, another possibility

I really wish I could fly to Lyon right now to see this exhibit by Luc Schuiten, a Belgian architect. The link takes you to a French website, but you can hit the arrows at the bottom of the screen to see a sample of his designs. This is such a playful exploration of how the cities of tomorrow could mimic plant life, or as he puts it, draw inspiration from nature for innovation. Needless to say, as a kid who used to dream of living in a tree-top city (among other places), I love this.
