TotemBall is a free XBox Live Arcade game, only downloadable by Xbox Live Vision camera owners.

The game requires the player to stand in front of the camera and wave their hands around to control the on-screen action. Anyone who has played the game for more than 2 minutes will know that your arms begin to ache very quickly, stopping you from playing the game for very long.

My solution is JazzHands, virtual hands for your computer. Simply point the LiveVision camera at the JazzHands window and control TotemBall using the cursor keys.
