I don't think I'd want to play it without a computer interface either; using physical boards would probably require three tables, with one for each of the two Home/Territory combinations shown and the third with all of the Open Faces. As I say in the text, this is less a proposal for an actual game than an illustration to help others visualize four-dimensional space.
I'm not sure what sort of further illustrations would be helpful, but I'll see if I can come up with something like diagrams with multiple Faces together showing moves (especailly diagonal and oblique moves) from one to another. (Well, I knew when I started that there'd be special challenges illustrating four dimensions using only two....)
