On the bight side, looking through the pics it appears that it was probably a junker headed for the scrapyard anyway. No interior, no engine, rear bumper rusted through, missing headlights etc. Would be a pretty safe bet to say the thing is pretty rusted out and probably has some pretty mangled panels hiding under all that "art". I think it looks horrible too, but at least I don't think the guy used anything that anyone else would have ever restored, and I bet he got it cheap so there was nothing to lose by playing around. Drew might be almost right about the crushed can being an inspiration, except maybe the can in this case started out about the size of a car.
On the other hand, What the hell was that dude smoking?? hahah
