"The walls between art and engineering exist only in our minds."

Not much I can think to say other than "Wow!" Take thirty seconds to watch this. The artist/engineer has a website here. I think "eccentric" may be a good term, although it's tough getting a handle on the man behind the machine translations into English. ("Hanging at his cord between to high buildings" is one example where the automated translation had a slight hiccup. But I suppose the point isn't that the bear doesn't dance well, but that it dances at all.)
