I think I need to show this to my wife, the architect. It looks like you've got a beautiful example of a parti diagram there("You can't really explain it, but you know it when you see it.").

Seems well suited to creating, say, a Halo level or a dungeon crawl, or, you know any kind of floor plan. It also seems like a good mandala to contemplate whilst writing up an RPG scenario or an insane story plot. Sadly, I'm buggered if I can figure out how to apply it to my own forte, planetary maps...

Still pretty broadly useful. As Midgard says, a useful abstraction. I, too, would like to see some examples of its application to maps before registering a judgement.
