I was looking at my Sudoku Rubix Cube and realized I could use it as a template for interlocking geomorphs. The orientation of each tile relating to a geomorph numbered 1 through 9. I'm going to have to experiment with this idea. Obviously 9 tiles is not enough so perhaps theres 6 sets of 9 since it is a cube. (9-a through 9-f). By manipulating the cube an endless city or dungeon could be generated.
Edit* I was fixing the link above when I came across THIS! Oh hell yes!
The mind boggles.
Uh-oh. Boggle Dungeon? Scrabble Dungeon? I better stop while I'm ahead.
