I recently got into a conversation with a geographer on the use of shading to
accentuate relief on maps.  What it boils down to is that a good job depends a 
LOT on the artistic skill on the cartographer.

Have any of you played with fractals to demonstrate relief?  What I have in
mind is using an arbitrary light source on a mountainous statistical surface, 
irregular illumination on the leeward surface, and projecting the surface
orthoganally onto a plane.

The geographer hadn't heard of any use of fractals for this type of relief,
although he said that he'd heard of people using fractals with population 
graphs somehow.
