Reader JD passed along a link to this cool site, Microdungeons by Tony Dowler. Microdungeons are very stylized representations of partial or entire dungeons, done without a map grid but intended to inspire referees when designing their own sites. I think it's a very nifty concept and hope we'll see the site take off in the coming months. I know how difficult it can be to stock a megadungeon and having a supply of bits and pieces to riff off of like these is a terrific boon.
Take a look!
