The Upside-Down Moon

I was listening to the excellent Naked Astronomy Podcast, and they alluded to something that had never ever occurred to me:

If you are in the Southern Hemisphere, the Moon is the other way up, because the Moon is exactly as it is here, but YOU are the other way up. So when it is a D-shape here, it is a C-shape there. And if you are at the Equator, it is a boat, or a canopy, or a pair of horns pointing upwards or down, and all the shapes on it are the other way up, so the mark that looks like a mouth, is more like eyebrows.

It had never ever crossed my mind. But I think it must be true.

Ever compared a turkish flag with a pakistan flag? Or a swiss medialuna with a argentina medialuna? :)

No, but what delightful ideas for further research!
