dutch artist theo jansen makes some really fascinating work. begining with a functional ufo that he flew over the dutch town of delft in the 80’s he’s moved on to what he calls strandbeesten, translated as beach animals. they are pretty amazing. modled in the computer and adhering to an evolutionary design principle (namely whatever works is reproduced in the next generation) these large scale sculptures utilize wind power to “roam” the beaches. you have to watch the video’s to get a sense of them. not much out there to be read about him (in english at least), but i did find this one bit of artspeak on the subject. thanks to rich for the link.
