Destructoid has a project to use the Nintendo Wiimote on Windows.
Carl Keener is a beast. Not only is he responsible for GlovePie, a programmable input emulator that allows you to utilize speech and boiled cats as joysticks, but he has also reportedly created a fully functional Wiimote Bluetooth driver for Windows as a little add-on to his masterwork ... without actually having a Wiimote! Isn't that something? Now if we could only fix him up with this lady we could have a far more interesting development..
