We've featured Dutch artist Theo Jansen's amazing kinetic sculptures a few times before, but they're so cool that we'd just have to showcase them again.

This time, it's a truly fantastic clip of Theo Jansen showing his creations at the 2007 TED conference. He even told us the secret in making the sculptures walk (it's in the tubes!) and think (with a rudimentary binary counter).
