Yes you will have to play with it.  But I just wanted to give you some 
concepts like a) media statements can be stacked b) a density pattern 
using granite or similar with an appropriate map will give the particle 
look you might be wanting.

I posted a more complete example of the code.  I haven't touched that 
project for awhile now but I remember the look was a delicate balance 
between the lights and the media parameters.  And the media effects 
would be cumulative so if I took out one of the density patterns in the 
stack I sould have to adjust parameters in the other patterns.  I had it 
all in a "lightscamera.inc" file which I have posted for you on 
p.b.scenefiles.  I threw in the necessary stuff so that the file can be 
rendered alone to demo the media.  By boosting the light excessively you 
can see the particular effect more clearly.  Back when I was doing it I 
was trying to get the look of harsh but quickly fading underwater 
halogen lights.  Some divers on the group here were giving me advice. 
Maybe you'll be able to pick it up where I left off.

Luck be a lady.
