I saw the new Jungle Book recently, and got jealous. Why? Because they rendered entire animals for multiple frames with fully animated hair. This dumb goat head crashed Blender more times than I could keep track of. Nevertheless, it is the fruit of my labor. I think The Old Goat is really going to enjoy this picture (but let's hope it still qualifies as a "composed" artpeice).

Here are the nodes for this goat's hair.
And this is a node system for the goat skin (basically the mesh that lies below the hair).
