This is a WindowMaker dockapp that displays a graphical representation of the phase of the moon, plus additional astronomical data such as rise/set times, orbital data, orbital elements, etc (if you click on the image multiple times). Probably most of the data is not that useful, but what the heck :) WWW: http://www.cs.mun.ca/~gstarkes/wmaker/dockapps/time.html#wmmoonclock
