The co-founder of Glitch developer Tiny Speck, Cal Henderson, has peeked through some of the World of Warcraft game’s files and extracted textures in order to create the World of Mapcraft – the game set out to be like Google Maps.
The game includes the land of Azeroth, Outland, Vash’jir, Deepholm, Battlegrounds, Dungeons, and “slippy maps” that are zoomable and draggable.
The World of Mapcraft also includes all of the changes throughout all of the different expansions and you can also look at the classic views of the game maps as well.
For those of you who are interested, Cal outlines his complex process on his blog: http://www.iamcal.com/world-of-mapcraft/
