Argon
Argon - the MUD mapper
Argon lets you (the player) create, save, load and edit maps. I expect these maps will be mostly useful during gameplay in online MUDs, which is why I wrote it. Some RPG tabletop gamers might use it as an aid to make dungeons.
Here are a few maps to play with:
Sample map 1
Sample map 2
Sample map 3
How do you use it?
Most room creation can be done from the keyboard. The standard directions (N,E,S,W,U,D) will move your active room around, creating rooms as you go.
You can pick the pen up by mashing the 'p' key. Putting the pen down somewhere else will place a room there with no exits, ready for you to move again.

Here's a suggested map legend:
Why "Argon"?
I often pick names for projects from the periodic table. It's happens to be a noble gas and happens to be similar alphabetically to Arctic, which is the impetus for writing it.
This doesn't help me with my style of MUD!
I'm interested in making Argon useful for as many MUDs as possible, but If there's a fundamental reason to why these maps can't work for your situation (like your grid uses hexagonal tiles), there's nothing I can do.
