So here’s the deal. Listen to a music in iTunes and launch the application. Hachune Miku would appear on the Dock and will swing her leek (negi) on the dock according to the rhythm of the song (I think it follows the BPM metadata on iTunes)! Click her to reveal iTunes controls. This application is fairly simple and is universal. That means that PowerPC Mac users can still use this program. The minimum requirements of the OS is Mac OS X 10.3 Panther.
