The Nonvint Falcon, seen here with optional pistol grip, is a 3Dimensional controller that has now been added to the supported controller list for Valve's Orange box series of games; including Team Fortress 2, Half-Life 2, and Portal.

The controller is controlled by a small spherical grid attached to three robotic arms.

Released in 2006, the Novint Falcon changes its weight and movement dependant on what weapon you have selected in game. There's also a tonne of force feedback, with damage and kick back when firing affecting the player directly.

Left 4 Dead, Counter-Strike: Source and Day of Defeat will also soon receive similar updates to make the controller an available option for players.
