Thanks for the link. While it does indeed looks nice, it's not what I had in mind. This is basically isometric 2D. You're looking at a plane. Things that rise up, like pillars, are not shown. You could not see that dam the way it really looks like in my linked picture.

We're getting there. mifki's working on getting multilevel rendering for basic tilesets (http://www.bay12forums.com/smf/index.php?topic=138754.105) and then that will be exploring 3d. Stonesense itself is headed in that direction, see the most recent forum page: http://www.bay12forums.com/smf/index.php?topic=106497.1035
