BlueTunes

BlueTunes is a program that will allow you to use the Nintendo remote (Wiimote) as a remote control for your computer music library (Windows only). Using bluetooth technology, the Wiimote will allow you to control your iTunes collection from 50 feet away. Walls and floors pose no problem at all. Even the Wiimote's motion sensing is utilized - shake the Wiimote to the right and the next track is played. Best of all, the BlueTunes software is completely free. You will need to purchase a Wiimote if you don't already have one (a Nintendo Wii is not needed) and a bluetooth transceiver (if your computer isn't already bluetooth enabled).
