Theo Jensen's Strandbeests

Here's a really excellent artist who blurs the distinctions between engineering, art, and philosophy. Theo Jensen has set out to create "life" from silicon and PVC, creating ambulatory works of art that react to stimuli and can move to evade danger. Irrespective of  Jensen's philosophical argument, the engineering (and art) in his work is certainly beautiful. Check out his work on the BBC [link] and a related TED talk [link].
