Now I have had two days of break from this calendar. So here comes a few posts in a row.
The True Size is a tool similar to the Mercator puzzle I posted two years ago, in that it makes it possible to see how the different countries change in size away from the equator due to how the Mercator projection works. This projection was originally meant for navigation at sea, so any line between two points have the correct compass direction, but the countries do not have the correct area.
