After selecting CyberFlair 3D Impressions as your Windows screen saver, you get 3 personal screen saver file slots that you can save your designs to. When Windows starts the screen saver, one of the slots is randomly chosen for playback. You can even mark individual slots as inactive for when any design is not required.
The Professional editions also allows you to have 3 Global Screen Saver Slots that are made available to all Windows users on the computer. This allows for easier deployment of your corporate screen savers.
