You can change the map type.  From the docs, section "3.5.12.7.2  The 
map_type Option", you can read:

"A map_type 0 gives the default planar mapping [...]
A map_type 1 gives a spherical mapping [...]
With map_type 2 you get a cylindrical mapping [...]
Finally map_type 5 is a torus [...]
Types 3 and 4 are still under development"

I'm not sure if it's possible to use normals as references in to 
pigments, which is basically what you're asking.  However, the following 
might be possible:

1. Compute a function for your normals, based on the location of a point 
on the surface.  This is easy for some shapes (ie a sphere, where the 
normal of a given point is the location of that point scaled to be a 
unit vector), impossible for others (meshes), and somewhere inbetween 
for others.  If you know the exact shape you would like to use, you can 
post here and we will try to help you out.

2. Use this function as your pigment.

3.  Use a spherical image_map.

PS This might be one of those times I'm full of it, so take this 
suggestion with a grain of salt.
