Hmm. You know, I was just looking at it again. There's no information on how it was made on that site. Just the picture. But I've got a hunch, and I think it's a good one. I think this was built around some kind of rudimentary wire frame. Because while each individual piece would hold up on it's own? I don't think the whole thing would. It would collapse or fall over. Particularly at the hips, knees and feet. In fact, if you look at the floor, there is a cross-piece under the feet. I think that's the base for a pole that runs up the "spine" of the thing.
Not to say this isn't still DAMN cool.
