Bogie has produced some amazing little nuggets for us. I propose that we hold a mapping challenge wherein one must make use of one or more of the elements from this thread

I would think that anything in the thread would do, and even that if Bogie put new ones in after the contest had started that they could be added if appropriate. But there should be a rule of not bugging Bogie to make things specific to your challenge map. You can build up your map however you want to, as long as it incorporates things that are in the thread.
