For the purposes of an Arduino jam session, Kristof van Opstal made an electronic version of the "buzzwire" game. This is an electronic version of the loop around the curly wire game - where you win by moving the loop from one end to the other without bumping the wire. Kristof's version added two servos which were used to alter the wire for the opponent if you made a mistake, adding a twist to the game. Not a bad effort considering the time constraints involved. Here's a short demonstration of the game in play:
