    I don’t quite get this. The human head, like the globe, is not flat. Shouldn’t that be reflected in the projections? When projecting the earth in Mercator, we see the whole earth, not simply a “profile” of earth. I would expect a projection of a head to include the whole surface of the head, not a simple profile. How is this actually factual?

      This isn’t representing projections of a human head. This is representing projections of the globe if the globe had a giant human head drawn on it instead of the continents.

        But then you have to figure out how to transfer the drawing of the head onto the curved surface, and how you do that is going to determine how the projections look.
