use the wii remote on your pc
playing games on your pc normally means using a keyboard, mouse, perhaps a joystick or a gamepad. and that normally works just fine, but why should you just stop therer?
with some help from a program called GlovePIE (glove programmable input emulator), you can use head trackers such as TrackIR (
www.naturalpoint.com/trackir 
), virtual reality gloves, such as P5(
www.vrealities.com/p5.html ), and even Nintendo's Wii Remote, whether or not the games themselves would normally accept them. There's surprisingly little effort invoved in making this work, just as long as you've got a suitable PC which is Bluetooth-enable, with DirectX 8 or later, and running windows2000 or xp.
Start by downloading a copy of GlovePIE (
http://carl.kenner.googlepages.com/glovepie ), then unzip the file into a folder of your choice and run it - there's nothing to install.
GlovePie doesn't know anything about the wii remotes itself, but relies on scripts to get everthing working. you'll find a suitable script at Vkapadia (
http://www.vkapadia.com/wii/windows.php ).
Click File> Open in GlovePIE to load the script. and that's it.
you should now be able to use the wii remote - or whatever other device is handled by the script - as a mouse, in windows, games, or any other application you like
