I have gone on in previous posts about the projects and the intentions I have with it. If you would like to read more about it then I suggest that you go here: Shameless project plug
I have started working on an isometric view that will allow scaling and in the future panning. All of this requires me to build an overhead grid that the isometric view and renderer will plug into.
If you are interested in the project then I suggest you fork a copy or get in contact with me. All of the information can be found on the repository wiki pages.
