I'm surprised that this script hasn't been more discussed here! It seems to be a update to Ajax's Pose Underground but with some excellent updates and new features. for one it doesn't require being run thru another program to setup for the script to work. Just launch the script in Poser 12 and it will open a small panel with several sliders and parameters. Then choose and starting group, any group with a following chain of other groups, work the sliders and the chain with curl in the x,y or z direction. Teh documentation shows it used for things like ropes whips and tails but I imagine with some experimentation there may be many other uses that will develop especially in the clothing area. 

You can not save the actual movement dials in a figure (at least not as far as I've been able to find so far) but you can create a morph target that takes advantage of the final shape. I'm just starting to play with this, but I was wondering if anyone else has used it and what their thoughts are on it?
