I haven't used a screensaver in years. But I think I could make an exception for an OT saver.
How about another mode where it just fades in and out to places (like the sunset beach) and just slowly pans around at a certain part of the day with the waves and the soon to be ambient sounds. Then to a mountain range, then to the grand canyon, then from the moon, etc etc. Maybe mix in some slow path flying. I probably wouldn't use my computer for hours.
