A solution to echoing empty rooms in a dungeon

Some people might remember that I have written before about the empty dungeon. For some people that is not a problem. They like the exploration of the dungeon environment to be a resource management challenge. Personally I like the idea of the challenge, but I have been thinking of "compressing" the experience a bit. If nothing else, it's variation. Right?

Ken St. Andre posted this on his blog a while ago. I had opened it in a tab on my browser and did not get around to reading it for real until now. That is a neat idea on how to do the "compressing" of your dungeon.

For those who want the executive summary, the idea is to make each room a index card, shuffle and deal a matrix of cards and those are the levels of your dungeon. Nice idea.
