Since I have had this Win7 system I hardly run savers now (although I do love Lagoon the touchscreen screen saver by Microsoft Surface).
The Saver should compliment the Dream file. It is my understanding that dreams run on the desktop (the workspace) so the animation should be slow, consistent, and not interfering with the workspace.
I was told once..."A good dream should give you the "feeling" of movement without it making you stop what you are doing to watch it."
Screen savers are entertaining and to screen saver users they can be an escape from the workspace.
I guess that means I have to start doing screen savers.
Or have someone else do them.
