Max Headroom was an actor, not an animation. I think his name was Matt Frewer, although I'm not sure I've spelled his name correctly. There was probably some computer processing involved, but I don't know what kind of process was used....

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.
