“VirtueDesktops” is a virtual desktop manager for Mac OS. It offers features, eye candy and configurable options that no other desktop manager on the mac has added yet, and is under active development. It is based upon DesktopManager, which is a lighter, less feature-packed virtual desktop application.

This is the best desktop manager for OS X. Superior to Desktop Manager. Nicest feature: Command-Tab will switch desktops if you select an application that is not on the current desktop. Ver' nice.
