Jsut some advise, a GREAT program to use to carveor "engrave" somthing is Bryce. You can either make a grey scale in Photoshop and import it, or use teh terrian editor in bryce directly(photoshop would be easier to make the grey scale casue you can use teh text tool). It also turns out really great. If you don't have Bryce, then download teh free trial fomr Corel, i am sure 30 days would be enough to learn to use it. For help, just check for tutorials. Here is an example using teh terrain editor. I know this is a photoshop forum, but i still wouldliek to help. And besides, you CAN use photoshop(many ppl do) to carve out the initial design using greays and white.
