I don't always explain myself well :( The shading function is just one
extra line of code, and really needs some more work.

Yes, it would be cool, but you can't apply it to any object. Mine works
because it uses almost the same function which produced the isosurface
in the first place; the surface is intimately tied to the shader function.
