Hesperus HWG Edition for Winamp 3. This is not a complete skin, but it is my entry into the hardwaregeeks skinning contest. Once this skin is complete, it will be named Venus and added to my Solar System skins series.
If features a sliding mode interface, over 20 color themes and vents that pulse to the beat.
