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.
