Yod'm 3D is a portable 3D virtual desktop manager. It does for Windows what Beryl or Compiz does for Linux. It utilizes a 3D rotating cube to allow the user to change desktops and can manage up to four desktops. Best of all, Yod'm 3D can be run portably from a USB device such as a flash drive or external hard disk.
