LunaSaver is a simple screensaver for the Mac OS X computer system. It was created by the same developer of the Lonesome Electric Chicken application for Mac, also known for its simplicity.
The LunaSaver screensaver displays the moon with its current phase, along with some other detailed information about the moon including its position, its size, the magnitude and its total distance from the Earth. It doesn’t miss information about illumination and the number of days until the new moon or the full moon either.
There have been some minor bug fixes for the screensaver regarding the graphics and it is now at version 1.2.4. Requirements for LunaSaver: PPC / Intel, Mac OS X 10.3 or later.
