Dungeons & Dragons Porn -- Amazing Homemade Maps
By the way, if you are tired of killing time (or your kids killing time) on airplanes watching movies, this is a solitaire pen and paper take on D&D. Every time you open a door there are 36 possible rooms/corridors beyond that you resolve with a die rolls, then more rolls to determine encounters. Requires a sheet of graph paper for the dungeon to get mapped and to track character skills/etc.
