I was delighted to see that molecular models with electron densities have
been done with POV

How about a media density function based on

I'm not sure how to use !n in Pov-Ray though.

n! is factorial. It's the product of all integers lower or egual to the value of
n: n*(n-1)*(n-2)*....*1
0! = 1 by deffinition.
1! = 1
2! = 2
3! = 6
4! = 24
5! = 120
6! = 720
7! = 5 040
8! = 40 320
9! = 362 880
10! = 3 628 800
11! = 39 916 800

You can use a macro to make the calculations, or use an aray that you fillup
with the results.
