Nice!

Why is it dark on the inside?

Also, I'd consider somehow making the letters be light sources.

Have you 'cut out' the letters or are they just an image map?

Thanks!

there is no light illuminating the inside, all the light comes 'from' the
lettering on the outside of the ring.

Very difficult, but I have sort of made them light sources. See below.

The letters come from a png image with the background solid and the letters
transparent.
I then mapped them to a hollow cylinder(with no_image and no_reflection)
and put a point light at the center of the cylinder. As you would expect,
the light shines through the letters only.
I then made a very thin layer of scattering media with a high density where
the surface of the ring is, making the light shinging through the letters
visible (you'll notice how the lettering appears brighter at the sides of
the ring)  I put another sphere of lower density scattering media outside
this to pick up more of the light rays as they shine on.
The ring itself is inside a light group so as not to pick up or block any of
the previous light. I put an additional light inside the light group at the
centre of the ring projected_through it to give the wood below it a little
illumination.
The letters appear to project back into the ring a bit because of the
reflection of the light rays travelling through the media.

A spoiler for the movie?  Isn't that a bit like person yelling
at you for when you gave away the end to Titanic?  Come on,
isn't the end common knowledge? ;)

Of course.  But I have never seen Titanic, how does it end? ;)

BTW Darth Vader is Luke Skywalker's father!

It sinks.  Poetic license, I guess...

Frodo is Luke's uncle!

I think he meant spoiler for the SCENE, not the Movie <G>

Oh oh post source. I've been looking for some good examples of the new
stuff.
