Hi

Back in 2003 Jaap Frank made some nice and interesting media images that 
might be relevant to you.

See this thread:
Newsgroup: povray.binaries.scene-files
Subject: Quantum Waves in Media
From: Jaap Frank
Date: 12 Jan 2003 04:45:23

Here's a link to that thread in the web interface:
http://news.povray.org/povray.binaries.scene-files/thread/%3C3e20f2e3%40news.povray.org%3E/

You'll find both images and code in that thread.
