I am currently in the process of re-working some base maps from the Donjon (outstanding random generator, btw) and put up a sample page with no decorations. I have several other maps to work on before they are ready for release, but they are all about this size or larger.

It is fairly rough, obviously, and I will be making some further changes as I don't care for the separation between rooms of one square in all cases.
