I tried out Nyko's version of their Wireless Nunchuck for the Nintendo Wii, and it required the user to wind the cord around an apparatus that connected to the Nunchuck.

The more improved version, the Kama, works very well for games such as super mario Galaxy, as well as Wii Boxing. The Kama is completely wireless, so now you don't have to worry about wound up or getting tangled up in the cord anymore.

The Kama requires 2 AA batteries, and has some really cool transparent buttons. You can purchase it on the Nyko site for about $34.99.
