[Edu-sig] Fun geometry w/ Python's help

[Kirby Urner]

Greetings all --

Just thought I'd share results of a project with other
Pythonistas.

Here's a POV-Ray graphic [1] I generated earlier today
using Python to write the script:

http://www.inetarena.com/~pdx4d/ocn/graphics/w1000.gif

What we're seeing are balls in a cubic close packing (ccp)
out to distance sqrt(1000) from the origin.  Color coding
indicates different distances, with orange balls being
at maximum distance.[3]

Source code is here:
http://www.inetarena.com/~pdx4d/ocn/python/ccp.py

Note I'm also importing modules coords.py (a vector
implementation) and povray.py (used to write vectors in
coords to POV-Ray).  Both are available at same URL.[2]
