I just found POV-Ray yesterday (well, day before yesterday at this point).
Thank you to those who made this available. I'm in awe and full of
excitement at the things I'll now be able to do.

Working on a concept I read in a novel once about common areas that were lit
by refracting pools in big underground rooms to escape the heat of their
triple suns.

It's lit by a single light source, far outside this room. It will eventually
be lit by three light sources, all outside the room. The column is a hollow
tube (or sets of tubes to get the look right). The innermost one is
mirrored. I'm thinking of changing the room to a sandstone dome, and of
course decorating it.

I tried quite some time ago to put together this same concept in 3dsmax and
it failed the task miserably. I thought I would never get a chance to try it
out.

Welcome :)
Well the tradition is to post a reflective sphere on a checkered plane as
1st post and you just missed the sphere :)
We'll say it is "far outside the room" ;)
Nice idea though if you want lights to really light your room after
reflections, you'll have to use photons and I guess it'll take long to build
a photon map for multiple relections.
An other way is to fake it by adding an arealight at the output of your tube
and/or use radiosity.

You couldn't add a light while you were at it?  ;-)

Seriously, it's way dark.  I don't see any light in your scene, it looks 
like ambient only.  But do you also have:

global_settings {
  assumed_gamma 1.0
}

In your scene?  If not, it could also explain why it appears so dark to us.

Welcome!

I've been using POV-Ray since the day version 3.5 came out, over a year ago.
In the beginning, you'll feel like you can do ANYTHING!.  It's a wonderful
feeling that I miss as my scenes become more complex.  (Yes, I still create
scenes, I just haven't posted anything in quite awhile, because I can't seem
to finish anything. :-p )

Thanks for using a j-peg as your second image.  PNG's don't compress as
well.

Your room isn't lighted very well.  You mention that the light source is far
outside?  I think all of the light is simply from ambient light, which gives
it a much less realistic look.

My best suggestion is to run every single one of the scene examples.  Go
through the tutorials.  Learn what radiosity means and how to use it (and
why it's so slow) among other things.  Use techniques that you learn from
the examples to put new ideas into your scene.  Eventually, it will turn out
quite well.

Good luck!  I hope you stick with it!
