At least you would know what you're talking about, Bill - it would be one book I would be in the queue for at two in the morning in the dead of winter outside the bookstore, freezing but not even feeling the cold.

In the meantime, I'm kinda putting this (probably useless) page together for this group of which I'm a member (Poser for Dummies... I'm trying to explore each node, changing one parameter at a time just to see what it does and rendering. Probably (actually, definitely) useless to this group, but there's heaps of ooos and ahhhs as lights are kinda going on for us Dummies. Including me.

You can see this lame effort here. I repeat: this is not a tutorial, it's an exploration, with hiccups and bumps and wrong turns along the way. Why do it? Because my partners in crime see the exercise as valid and because it is inspiring them to do some exploring on their own.
