I kind of doubt you can apply the phong (or whatever) lighting model to
media, since media does not have surface normals. It is a volume effect and
doesn't even have a surface as such. But perhaps you know better.
You should be able to apply a standard colour pattern (bozo etc) to your
fur, probably by using muliple medias in a container. I haven't experimented
much with this, though, so I can't be sure.
If you use the superpatch you _might_ achieve the fur effect with a
isosurface, since you have apparently developed a function that gives this
hairy appearance. If so, you wouldn't need to worry about applying lighting
models and textures.
Oh, and about your furball - it really does look like fur. A bit
transparent, but that should be easy to fix. Can it also make hair at
different angles? And how long does it take to render?
