Cedar coffee table under construction

Well I started off building a shadow box coffee table for Texans to put together their own Texas style collage. I now have a new idea; merging the red cedar with a granite tile. The top will have an outside frame (1x6) cedar boards surrounding the granite tile in the center. The legs will be 4x4 red cedar posts, so the only color transitions will be between the tile and the cedar. In the first table the color transition is between the legs and the main body of the table.

I thought I would get a little creative and etch a unique scene of wildlife in the granite to give it a Texas twist. The problem I am running into is figuring out which method to use when etching the scene into the granite with fine detail, giving it a nice clean crisp look.
After a little research, and talking to some local friends; I think the best way to go is to have a template cut out of a sticky vinyl. The next step would be to place the vinyl template over the surface area of the granite and then sand blast over the vinyl. After sand blasting and removing the vinyl, there should be a nice clean crisp wildlife scene.
Below is a picture of what I have put together so far. After I finish up with my finals this spring semester, I plan to finish this project and will post a picture of the finished product. For all you other craftsman, I will let yawl know how the process turned out.
