I need to add that your grammar is really nifty, and it would produce perfectly valid layouts...and on further review the idea of transformations on a basic pattern is exactly what you proposed. Sorry for misinterpreting -- entirely my fault. However I still wonder how you take that grammar and extend it into 2 and 3D, which as I recall requires some notion of state. My Finite Automata class is a bit rusty, so I forget the term... but I think I'm thinking of this being "not well formed" or "non-homogenous" or some other such phrase. Basically indicating transformations and rules that couldn't be reduced into grammars because of notion of state or other conditions. Darn, I hate forgetting college so fast :)
