I am curious too about the border. Its so neat with all the buildings having arches so symetical and bulbous domed roofs so perfectly rounded. Its so arty and yet technical. If I even deluded myself that I had the ability and wished that I wanted something similar to that then I would have to build the whole damn thing in sketchup or something and technical apps tend to sap the artistic side of things. Do you use a CAD type package for this or is this still all done in a paint / 2d vector app ?
