Here's a way to combine two of my favorite addictions. This fellow put up a video on youtube explaining how to use the Wii remote to control World of Warcraft. The video is in Norwegian but the step by step instructions on the axemen.org site are in English for those of us who didn't have the opportunity to learn anything but Spanish in high school.
"I figured I could make a howto - on how to connect your WiiMote to your windows system, and using it to play WOW or any other game you would like to play. Since I only own a Bluetooth dongle, this tutorial only covers how to connect it via bluetooth and using it to control the mouse without IR."
