Forbidden Island interlocking card plate

If you have never played Forbidden Island by Gamewright Games, I cannot recommend it enough! It is relatively inexpensive, easy to set up,and easy and fun to play. The idea is that the players (2-4) are not playing against each other. You play against the board and cooperation is the only way to win. Take a look at it here: http://www.gamewright.com/gamewright/index.php?section=games&page=game&show=245

This is an interlocking plate that can be used to keep the 'island' of cards in
