Fascinating. Had to look it up — the photos of it are mind boggling.
I have to say though, from Wikipedia, sounds like there are only a few of them? Sort of one-offs, each of them (so to speak). I kind of think that might disqualify them.
(I know this comment is not exactly in the mood of HN, but this is the one thing I never fail to think of when someone mentions the Bagger family of murderous machines!)
