Theo Jansen is a genius.
For the past 10 years he has been creating new nature, with plastic of all things. His creatures are called strandbeests and he envisions them roaming the beach in herds, surviving on their own. It’s people like him that I find really fascinating, he’s spent a good portion of his life on these things that have no real discernible purpose, surely the principles can be applied to lots of other mediums, but that is not his goal. I love that, check out a video here. His own website here.
