They work and are useable. The demo file optics.pov was designed on a 
"blue and white" Power Mac G3 at 350MHz with 384MB RAM. They are highly 
memory intensive though...storing photons throughout a volume takes a 
lot more photons than storing on a surface. It might be your tank is 
just too big. The blackout sounds odd too...did you get the media 
looking good before you tried photons? The number of photons won't 
really affect brightness, just the fineness of detail in the caustics.
You definitely need to reduce the number of media photons if it is so 
hard for your machine. Buying more RAM wouldn't be a bad idea either.
