This excellent video from 1947 uses a grapefruit show map distortion

frauenfelder: frauenfelder: To see the land masses as they are, you need to build a giant hollow globe that you can stand inside with your head at the center so that all points of the map (painted on the inside of the shell) are the same distance from your eye.

What’s wrong with just turning the globe? I mean, if you do make the hollow one you’ll need to turn yourself to see them all, which has the same effect but is harder to do.

The video is a cute find. I wonder what projection the turnip map actually corresponds to. They compare it to Mercator, but that actually has the poles blow up vertically as well as horizontally. It’s a difficult hour to think through the mathematics right now, but maybe it ends up being Plate Carrée?
