No one linked to this xkcd What If? article about an alternate Earth where the continents have been rotated 90 degrees with respect to the ecliptic, so that Antarctica is now on the equator.
I guess this means either (A) not many people know about this xkcd feature, or (B) no one sees this as an interesting map possibility. Just think: Ice Mayans! The Picts get to live on a tropical island!
