That's not impossible at all.  There's some question in my mind about how to allow the user to define a path properly, but I've already been thinking about a script variant which might follow a user-defined path, although not exactly in the way you suggest. 

I'll have to think about the idea, but I like it.  :thumbupboth:  The main trouble is defining the path.  Since Poser 8 and Poser Pro 2010 have a bug which interferes with certain Tkinter GUI arrangements, some new approach will be needed to permit a path to be defined.  I'll start thinking about different possibilities.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

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.
