An anisotropic shader would have different effects depending on not just
the local "elevation" of the incident ray, as is usual, but also the local 
"azimuth." Think of one of those Christmas ornaments that's wrapped with 
fine fiber and thus has a ring-shaped highlight.  I'm thinking such a thing
would require UV mapping as a prerequisite.
