For anyone who's got a Mac and wants to check it out, this is a board game engine I've been working on.  I've only got one working game so far which I've recently changed from simple colored boxes to something dramatically more pretty.  Eventually there will be multiple games and an editor so you can construct your own.  In the meantime if you want to mess around with some of the game parameters you can edit the "RulesDict.dict" file that gets created and change things like the board size, number of colors, stuff like that.
