Since the Wii's Wiimote uses Bluetooth, you can get it to synch up with a PC with a Bluetooth adapter. Someone's already started
creating a Windows driver so that you can use the little device with your PC. There's not much you can do with it yet, but this project should continue to evolve or someone others will begin working on one so that one day you too can be swinging your controller in PC games.
Thanks
