zzConstellation Screensaver displays a rotating view of multiple constellations along with their names.
All the constellations are presented with connecting lines so you can easily make out the shapes of Libra, Lupus, Sagittarius, Orion, etc. The display is broken into the eastern and western sky for easy reference. It also shows the ecliptic and galactic planes as well which is pretty cool.
zzConstellation Screensaver comes in a zip file containing a .scr, which is typical for this type of application. All you need to do is right-click on zzConstellation.scr after extracting from the zip file and select \\\"Install\\\" or \\\"Test\\\" if you prefer a quick peek before adding it. The screensaver properties window will pop up to configure your settings however this particular screensaver has no additional settings.
