Katana controller for PS2 game. This wireless motion-sensitive sword is the controller for a character in Onimusha 3, forthcoming for the PS2. The game itself is apparently recursive: you are asked to direct the motions of an avatar who is playing a videogame of his own controlled by a motion-sensitive sword, and swinging the physical sword-controller causes the virtual sword-controller to move, which, in turn, directs the swordsmanship of your avatar's character in an in-game game.
