This cool map (click to enlarge) comes from the All Nippon Airlines in-flight magazine. Tokyo was put at the top of the globe and every other point projected around it, radially along the longitudinal lines. So distances measured from the center of the map along the longitudinal lines are accurate, but all other measured distances are not. And the farther away a continent or a country is, the more distorted its shape comes out! (There is actually a map with this projection on the United Nations flag, with the North Pole at the center).
