World of Warcraft's Azeroth – think of it as Google Maps for World of Warcraft and its expansions thus far. It's all online right now, the work of Tiny Speck founder Cal Henderson, who extracted textures from the MMO's source files to piece together the interactive map you see above. You may recall Tiny Speck's own MMO, Glitch.
Just don't click on the map above and expect to be able to zoom in on the Isle of Conquest. You have to click the source link below for that. And if you're looking for more background on World of MapCraft's creation, Henderson has a pretty thorough blog post explaining it all.
