SliderDock

SliderDock is a freeware application launcher for Microsoft Windows[1] that uses a wheel-like interface to organize icons. When the user scrolls with the mouse wheel, the icons rotate towards a fixed point so the user can access a specific icon. Once an application is launched, SliderDock hides itself in the background so as to take up less space on the desktop. SliderDock was created with space in mind, and attempts to use the least amount of RAM it can when it's not currently on-screen. Like many other docks, it can also be customized with skins and icons from other docks.[2]
