It occurred to me that Martian Chess could be played with a Treehouse set and two Martian coasters. To playtest this, I've set up a game in progress on my wiki page sandbox:
http://icehousegames.org/wiki/index.php?title=User:Cerulean/Sandbox#Micro-Martian_Chess
It's open to anyone who wants to make a move. If you're comfortable with wiki code, feel free to take North or South's turn as needed. Don't forget to indicate the new player's turn.
If this works, then it also proves that the IceWiki can be used for remote IceGaming or playtesting.
