Of course this density model is nearly the same as the curvature model. The
clear difference is that curvature usually implies a 2 dimensional world,
while density is usually associated with 3 dimensions.

Ah, will you be using tensors? If so, can you explain me a bit about tensors
(in practical pictorial examples). I'll be in great debt...
