Moon
A simple Moon phase viewer for the XO laptop including Lunar eclipse information and effect. Its usefulness as a shared activity will make more sense once the planned Sugar bulletin-board/chat overlay interface is implemented, where children will be able to point out features and places of interest to each other.

Development
Moon is a standard Python activity that uses PyGTG for graphics and events. All Python is in an easily modifiable single file with a Sugar activity subclass that takes care of control and views, and a model class for Moon calculations. Code was ported from a Cocoa Mac application I wrote some time ago called MoonDock.

It would be good to have associated displays that explain some of the technical terms like, waxing, Julian, lunation, Selenographic, teminator, longitude for the schoolchild or anyone wanting a lesson on Earth's moon. --FGrose 23:00, 19 February 2008 (EST)
