This is a 3d printed world map based on ranks of countries by the Good Country Index 1.2 (2007).
You can find more information on wikipedia:
I have changed each color to a specific height. so, the heiger the altitude, the better the country.
It is possible to add color to the printed object too. but it is a work of art and I cannot do it.
This method can be used to show any index, e.g. GDP, population, ... about countries.
