Orbital Screensaver

1) Screensaver where the image is the desktop as you left it, but the color and shading and brightness go through a cycle simulating the daylight (or lack of) of a normal day. Possibly also simulating shadows of the icons as if the sun is passing overhead. Obviously this would have to be faster than actual speed (make that a setting), and give the option to have a clock superimposed in the corner to show the time as it passes

2) Same Idea as above except the perspective is changed. Instead of workspace being actual size and sitting on the surface of a planet, change perspective so that your workspace is the size of a planet. The screen saver simulates a star orbiting your workspace. (yes I realize that this is not how stars normally operate) The view is as if you are watching from the same plane as the star's orbit. You will see the star pass in the background far behind all of your icons and then watch the lighting change as it comes around to pass behind you lighting the desktop straight on.
