How can I make this look cool?

(Text = CSG. The S in particular was very hard; it involves 4 cylinders 
and 2 cubes. (?!) Lighting is radiosity (bluish) + 1 light sournce 
("sun", yellowish). Hmm...)

A touch of color would help. And so would cleaning up the edges of the 
letters. N is horrible. V is dodgy. The S is good.

Instead of using boxes, use prisms with linear_spline to make the letters.
This will make it easier to clean up the 'N'.

The 'S' could be done with a prism using bezier_spline to get both flat &
curved surfaces, but you need to know a thing or two about where to put the
control points.  If you post the code for the 'S' I can do a bezier
version...

Beyond that, using photons & dispersion could make quite a difference.
Radiosity won't have much effect on the 'glass' letters.  Unless you plan to
put more plain-coloured (not transparent or too reflective) objects in the
scene it would be quicker to leave it out.

Gaaarrhhh! What am I talking about?

Just use the text{} object in Povray.

Come to think of it, why aren't you using it?

Ever considered using a text object?
That apart, you may want to intersect your leters with a box. It will help removing
the extra edges 
on the "N".
Use a merge instead of an union for the "N" and "V" to remove those internal surfaces.
Try to change the camera position so that we can see the whole thing.
As is, radiosity looks like it's a waste of time. Using photons can have a dramatic
effect. Set your 
transparent objects as target with refraction on, reflection on may not be useful. Add
some dispersion.
Adding a faint coloration to the substance of your leters may help, use fade_color
color 
fade_distance 4 to 10 times the thickness of the leters to keep it faint and
fade_power some value 
to control it. It's place is in the interior{...} block.

Hmm... that could work.

Nah. I'm already quite happy with the S.

Quicker without radiosity, certinaly. But then the scene is vastly too 
dark...

I was thinking about adding some photos.

Well, I was *planning* to bevel all the letters in 3D... but I never got 
round to it. :-\

Yes, but I *was* going to make all the edges curved. (In fact, I still 
hope to. It's just that doing it requires about 12x as many objects...)

Yeah, I think you might be right there. Either that or use a prism...

Already using merge.

> Try to change the camera position so that we can see the whole thing.

Technically, you already can. (I haven't moddled the remaining letters yet!)

> As is, radiosity looks like it's a waste of time.

Image is far too dark without it.

> Using photons can have a dramatic effect.

Yeah. As I say, the original plan was to curve all the corners. If I 
manage to do that, photons are really gonna be good!

> Add some dispersion.

Sounds slow... LOL!

Mmm, OK. I'll try that...

   Use a fading light (fade_power 2) close to the text.
Make it an area light. Use photons.
   Just those, and it will look a lot better.

Hmm, doesn't Elefont bevel text for you?
