Graymer is a curiously-named utility designed to do one thing: display the various levels from Ultima Underworld as a screensaver for Windows.
It requires a copy of the game (e.g. from GOG) in order to work, obviously, but can be quickly installed and set up. Because really, who wouldn’t want to be able to enjoy a wander through the Stygian Abyss whilst staring at a dormant computer?
