====== Latitude Dependent Lunar Phase Shapes.  ======

===== General Description of the Simulation =====
The orientation of the lunar phase shape to the horizon (i.e., the position angle of the lunar shape) can tell us about the observer's geographic latitude. Therefore, from the photo of the various lunar shapes, students can estimate the location (latitude) of the observer. This is a simple 3-D representation of the relative positioning of the Sun, Earth, Moon, and the location of the Observer.

Waxing moon seen at different places on the Earth (Left: Equator, Middle: North Pole, Right: South Pole). Seasonal variation is ignored in this simple explanation. The left image was taken after the Sunset at the western horizon.

We can even mention about the liberation of the Moon in this topic.
