I don't know if this really counts but I have this part rubber part resin, posable figure of the queen Alien from "Aliens", I used to have Riply in her forklift suit too but that went into another person's science fiction collection a few years back.
Well, Queeny and Riply were often used for stop motion stuff, and it was a pain to get that awkward shaped alien to stand properly because most of her weight was in that huge crest and head. I would often give up and string her up by the head with fishing line to get her to stand and hold weight properly. It worked very well and if the line showed in any of the shots I could edit them out with ease in gimp or photoshop, however I'm not sure that fishing line around the neck would really do any good an Obitsu, BJD, anything human shaped and with so many moving joints. I think Queeny has a grand total of six moving parts, and they don't even have a very wide range of movement.
