OSXmoontool

OSXmoontool displays Informations about the Moon like Moonphase, next Full-Moon and Earth to Moon Distance.
This program is an OpenWindows tool which displays, as the icon for a closed window, the current phase of the Moon.

OSXmoontool also shows the the age of the Moon in days and hours and if you activate the "-t" switch, it increments very fast forward through time to display the cycle of phases.
