so i just went digging on you tube trying to find this advertisment i saw some time ago featuring an artist whose work was really interesting. he built these huge sulptures that "walked" on their own, under the influence of the wind. so i searched for "kinetic sculpture", and boy did i hit paydirt. the mans name is theo jansen.
here is the bmw commercial i first saw
and a few more videos of his work
this one is neat, horse sculpture project inspired by jansens work
wow, thank god for youtube, huh?
oh, there are more videos of mr. jansens work available if anyone is interested.
