Interactive toys has designed a prototype of a the NES game Duck Hunt for the real live living room hunter. It consists of a mechanical, flying bird and a gun similar to the classic NES controller. There is an infrared laser on the gun and a sensor on the duck.
Shoot it once and it stutters, shoot it twice and it stutters, and the third time you shoot it, the duck falls right out of the air. It will be available for $30 from interactive toys.
