can anyone help me get started on the media? I keep getting an entirely
black image.

If image becomes black when you put media, it may be that scattering_color
is way too high or the object containing media is way too big
could you show your material and container code?

well, right now I have this...
box{<-1,0,-1>*1e3,<1,1,1>*1e3 hollow
texture{pigment{color rgbf 1}}
interior{
media{
//absorption
scattering{ 1 (1-Tan) * 0.2
extinction .1
}
intervals 5
density{granite}
density{bumps scale <1,0.1,1>}
}
}
}
and it's not black, but it's taking approximately 100,000 years to render.

That's a prety big container. If the light_source is outside of it, even with that
reduced
extinction and relatively low density, almost all of it gets dispersed out and can't
reach whatever
there is to light up. Try reducing the density even more, or increase the light's
intensity: start
with LightColour*10 and work up as needed.
Using intervals 1 samples 100 can actualy be faster than intervals 5 when using method
3 (default).

One of the problems I had with a smaller container was that the tower was
casting a shadow on the inside of the container.

Have the container have a texture like
texture{pigment{rgbt 1}finish {ambient 0 diffuse 0}}
Totaly transparent, don't interact with light_source, no ambient = totaly invisible

It's taking forever to render the first line...
Here is my current version of the media - what's wrong?
box{<-1,0,-1>*100,<1,1,1>*100 hollow
texture{
pigment{rgbt 1}
finish {ambient 0 diffuse 0}
}
interior{
media{
scattering{ 1 (1-Tan) * 0.2
extinction .1
}
intervals 1
samples 100
density{granite}
density{bumps scale <1,0.1,1>}
translate <clock*10,0,clock>
}
}
}

Your computer clock has stopped - rewind it and try again.
