Blog of Holding: Random Dungeon Generator as a Dungeon Map Poster
This intricately illustrated 36" by 24" playable dungeon map poster encapsulates the 1e 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.
Even if you missed the <a href="http://www.kickstarter.com/projects/2040314005/random-dungeon-generator-as-a-dungeon-map">kickstarter</a>, you can still buy the poster!
