Hi all,
Scatha 0.2.2 for Mac OS X is now available for download from my Glaurung and Scatha page. Scatha is a "twin program" of Glaurung, and plays hexagonal chess. Most of the source code is shared between the two programs.
At the moment, Scatha's GUI is rather incomplete, and there are probably plenty of bugs. Many important features are missing, like game clocks, saving and loading games and the ability to set up positions. Nevertheless, even this basic version is quite fun to play against, and a useful tool for learning the rules of the game. When you click a piece, the program will show you the legal moves of the piece. There are several "Easy levels" for beginners. At the easiest level, Scatha makes random moves.
The GUI communicates with the engine by a straightforward modification of the UCI protocol. In the unlikely event that some other programmers want to add support for hexagonal chess to their engines and port them to Mac OS X, I will gladly document the protocol and help you make your engine run in my GUI.
