This is great!  I was just looking for something like this, last week.  I ended up re-mapping the irises, instead.

One problem, though.  Poser 5 doesn't have a Wave_2D node option.  Is there any way to wrangle the same effect out of P5, using a math function with sine, or something?

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.
