Well, since it's on a 2D surface, it'd look a bit odd...

BTW, I vaguely recall some very good sky_sphere pigments done using this 
technique. One advantage there is that you don't have any intersection 
or finish/normal calculations, so it renders faster. The layered pigment 
feature of sky_spheres seems to be overlooked far too much.
