While you know .com as the most popular top level domain, every country has a unique TLD of its own known as a country code. Here is the entire world in those country codes.
Available for $US30, Country Codes of the World is a 60 x 90 cm representation of the globe in which each country is displayed as its corresponding country code in a font size relative to its population. So countries with big populations appear as bigger letters on the map, and small populations look tiny.
It's a neat idea that really shows you the US's place in the online world, especially as China and India (.cn and .in) both look huge here, despite having been scaled down 30% to fit within their geography. [bytelevel]
