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.

Memory-wire-based headset. The Arriva headset uses memory-wire to coil securely around your head (Gizmodo compares it to an alien brain-sucker) and communicates with audio sources via wire, Bluetooth, or FM receiver. The "buy it" page is b0rked, so there's no way to tell what it costs.

Our patent pending headset is unique in design and functionality. No exposed wires increase durability. Flexibility allows for abusive use and storage without adverse damage. Best of all, the weave design fits any size head comfortably and securely. The "WRAP-RADIO" will NOT fall off. The design accommodates different "ear buds" and color specifications per your requirements. The headset can even be waterproof.
