After reading this post about the one page dungeon contest I was brain storming for fun ideas and one of the things I cam up with is a very simple one page dungeon that folds into shape with some simple scissor work and tape. Nothing super complex or detailed just an added fun element of 3d. Though I abandon the idea for that contest I did make a mockup for my own entertainment. I'd take a picture of the completed thing, but I don't actually have a printer. I did a simple black line version and one where a more realistic dungeon was raising out of a traditional pen and graph paper style map, the final one is just the ink friendly version of the first. There are no proper instruction to go with it, but it should fold into two unattached rooms approximate 3/4" per square with all printed sections facing into the dungeon.
