For those that are interested, the .ogz, -art.cfg and the texture files are posted at http://www.sendspace.com/file/grtvzl
as a .tar.gz. The compressed file is large (6.1 MB) due to the textures. I'll try to reduce the size of them, later. (It means going through each graphic individually and making sure that they are reduced to the lowest possible number without reducing the effectiveness of the graphic). You're welcome to play with the files, use, modify, or whatever as you like. Since this is a learning experience for me, I'm not concerned with fielding whether or not something should be put back into the overall map, though I might be interested in how you do something.
With regard to textures: The granite (finished and unfinished) textures are created from photographs of actual granite. The original photos were "do as you like" photos, from which "samples" were created, and modified to work for the textures. The textures, therefore, can be used for other purposes than just this map.
