Gamers rejoice! If you are one of the lucky bunch who snagged a Nintendo Wii in recent months, “Darwiin Remote”:http://sourceforge.net/news/?group_id=183966 is a neat, helpful program that utilizes your Mac’s Bluetooth technology to read the Wiimote’s signals and utilize them for good and awesome. For example, Darwiin Remote can map the Wiimote’s buttons to your keyboard, making it easy to use the Wiimote as a wireless controller for emulating video games, a method for navigating a slideshow while standing at a podium, or a control for iTunes when sitting on the couch studying.
