You can actually use the software yourself and see your own city through Prettymaps itself. It is fun to play with but unfortunately you can't save the image you create (which is a bit of a bummer) but it will definitely keep you busy for a while.
Work is getting in the way of our kitchen but hopefully I'll have some real progress to show you soon. For now I just keep staring at my tile and trying to imagine the finished product.
P.S. 20X200 didn't pay me for this, I just like the art.
