Calcium Fluorite Crystal Structure

In this video I introduce the atom positions in the Calcium Fluorite Crystal Structure.

Note that this structure can be correctly described as either:
 - a simple cubic lattice of anions with half of the simple cubic sites occupied 
OR
- an FCC lattice of cations with all of the tetrahedral sites occupied

Both are correct and equivalent, but it is very challenging to see them both so I created another video showing calcium fluorite using both approaches (https://youtu.be/AZ_tHBIBQWU).
