Paul Hughes has been making Dungeons and Dragons art at his blog for years so he wanted to generate a way for others to do so easily as well. The following project ensued:

This intricately illustrated 36″ by 24″ playable dungeon map poster encapsulates the Dungeon Master’s Guide’s complete rules for generating random dungeons: Appendix A’s four pages of charts are rendered into a flowchart WHICH IS ITSELF A DUNGEON. It’s like the Platonic dungeon: from it, all other dungeons may be generated. Or maybe it’s the Dungeon of Ouroboros. Or maybe it’s D&D’s missing game board. 

This is meme fodder if I ever saw it. You can support the project here.
