There are other ways to have some pattern in a media.
If you want a toroidal media, use a torus as a container. I've tested
that with a wood pigment as a density pattern and the result is interesting.
In fact, you can use just about any pigment pattern as a base for your
density.

Ok thanks a lot...
But i'm not able to build this kind of pattern can you give me a exemple ?
And for the "text/glow" do you have an idea?
Thanks again

In your sample scene, change your containing sphere to: torus{.5, .25...
Comment out boxed, spherical and cylindrical.
Add: wood rotate 90*x
Thats all!
You may try granite with this density_map:
[.75 rgb 0]// Mostly empty
[.9 rgb 5]// but with some high density spots
For the text, give it a transparent pigment: pigment{rgbt 1}
Then give it an unpatterned media. It will look like:
interior{media{emission 1 density{ rgb 1}}}}
That media will probably have to have a high density.

Scale the pigment by .5 give something more interesting.

One more experiment you may try:
crackle scale .4
density_map{[.01 rgb 2][.12 rgb 0][.7 rgb 0][.9 rgb<2,0,0>]
An irregular 3D latice with some red fuzy spots

That's working!
Thanks a lot. Now i "work" on text.
If you haves tips, no troubles i take then.

Could you please stop quoting the entire original article when it's not
necessary?
Just quote the *relevant* part of the original article (or nothing at
all if there isn't any specific short relevant part you are answering to
but you are answering to the original article as a whole).
Quoting the entire original article and answering at the end just
makes it more difficult to find your answer and wastes valuable server
space and bandwidth for no good reason.
