Here are two links to videos that came to my head after the first
session. The first one is about a giant ant colony. When you see those
small hills full of ants in the woods you may not guess how complex
those systems are. But this video shows a really amazing "architecture"
created by the nature of ants!
second one is from an artist from the Netherlands, Theo Jansen, who
creates huge "animals", moving structures that are not dependent on
anything else but wind and sun. Take a look! ;)
