Though primarily an interesting upside-down world map, you'll also find this map to be loaded with features and a useful reference.
This world map is produced in a colorful political style. The colors of countries are bright and pleasant, making the map an attractive piece to display.
Even though the overall style of the map is Political, Physical information such as natural features, mountains, rivers, and even 3D shading of terrain are also included in the map, making it a good all-around reference map.
The flags of all countries are shown too, which adds to the aura and information provided by the world map.
Quite simply, an upside down map gives us the opportunity to see something familiar (like a world map) from a completely unfamiliar perspective. By simply flipping the orientation of the map (south-up, instead of north-up) it's as if we are looking at the map for the first time.
This can teach us a lot about the importance of perspective and how our point of view shapes our perception of reality.
