Oh, thanks, guys.    I haven't posted for a bit because I'm distracted by trying to put together a basic dynamics simulator for the chain script.  I started out with what is evidently a euler integrator, which is a bad thing.  So I'm digging for alternate approaches, but there aren't any readily helpful examples and I'm having to build something slowly through trial and error, with periodic sidetracking into cursing & online research.  :lol:  I'm currently trying to switch to a velocity Verlot integrator.

Hopefully I can work something out.  The euler approach looks neat when it works, but the chain can too easily stretch until the links separate, while the flaws in the euler method prevent the application of adequate restrictions on the stretching.  (If you try, the chain explodes.  Which looks kind of neat, the first time.  :lol:)

So... working on it.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
