It's a two player board game my family made up a long time ago. It's kind of like a mix of chess, battleship, stratego, and it's got some unique things of it's own going on.
It's a computer simulation of a physical board game (linux, gtk + cairo). It's is also an actual physical board game, you can print out the parts of the board and paste them onto cardboard,and with a 3-d printer, print out plastic pieces to play the game with, or with a laser cutter, cut out pieces to play the game with.
The computer version doesn't do a whole lot that the physical board doesn't do -- for example, there's not much in the way of enforcing rules or helping out with the collision resolution (yes, collision resolution -- it's a strange little game.) There's no built-in communication, so you need to establish a means of communicating with your opponent outside of the game.
Source code for the computer version is GPL'ed.
Rules are here.

If you clone the repository, there's a src directory, if you go in there and type "make" it will build an executable, "dmost"
