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

Development
Moon is a fully Python activity that uses PyGTK for graphics and events. All Python code is in an easily modifiable single file with a Sugar activity subclass that takes care of control, views, and a model class for actual Moon calculations. The code was ported from a Cocoa application I wrote some time ago for the Mac, called MoonDock.
Release Notes
v7
Added French locale by Bastien Guerry (thanks!) Reduced frame padding to allow more space for longer French strings. Fixed encoding issue affecting one string in the po file for both FR and ES. Corrected missing newline from Juliana ES translation string.
v6
Now has a Spanish locale by Gabriel Menini (many thanks!) Removed service_name from .info, that spec went away a long time ago. Change methods from camelcase to make pylint happier...
v5
Cleaned up MANIFEST. Added extra licensing texts and activity.info fluff. Journal stores state for grid on/off and southern/northern view. Activity remembers last used defaults and will use them for new launches. GIT now includes the below Spanish name modification
v4
Now called Luna in the activity bar in Spanish locales. Still needs translation for spanish...
v3
Added a view toolbar. Feature added to display selenographic longitude and latitude grid lines (to help learning the terms). Feature added to toggle Moon image view between Northern and Southern hemisphere viewing location (rotates view 180deg). Textual displayed dates/times comply with local daylight saving rules and time zones (all internal calculations are in UTC). More accurate selenographic terminator visualisation (shadow) for waning gibbous & waxing crescent (corrected estimate for 3d curvature).
v2
Minor update to display information using your local time zone, instead of UTC
v1
Beta version with basic core functionality (text information, Moon phase visualisation, Lunar eclipse data & effect).
Testing (Yes)
Moon v1 has been tested on build 690, 691, 693 and various joyride builds on a B4 XO laptop.
TODOs
- Mouse over hover hints for major Lunar features
- Markers for interesting locations, view toolbar button, showing Lunar landings etc.
- State saving to Journal, for the new view options
- Simplify/clean-up textual data and information
- Improve information for the targeted demographic age
- Convert main view to Cairo to allow improved rendering
- Soft shadows
- Antialiased grid
- New daylight view feature (would be an estimate)
- Light blue to black transition of sky and Moon composite
- Translation work (string code is all marked up but not extracted for Pootle yet)
- Consider possible shared activity functionality
- Shared markers with text notes?
- Mini-month Lunar calendar (stylised icons)

It would be good to have associated displays that explain some of the technical terms like, waxing, Julian, lunation, Selenographic, terminator, & longitude for the schoolchild or anyone wanting a lesson on Earth's moon. --FGrose 23:00, 19 February 2008 (EST)
- In version 3, I've added an extra colour coded view showing a longitude and latitude grid along with compass directions - I'll probably extend this technique (least text as possible) in future versions (e.g with a view mode for labelling/highlighting the terminator edge in green). Hopefully this will help. --garycmartin 2:00, 26 February 2008 (GMT)
- It would be great if explanation (or link to it) for technical terms are provided on this wiki page. Without the knowledge it is very difficult to localize this activity on Pootle. --Korakurider 2:00, 10 October 2008 (JST)
