Blizzard has released the official World of Warcraft Desktop. The suite, created for Stardock Media by Apocalypse_67 and Adam Najmanowicz (lead developer of Stardock SkinStudio) combines both original artwork and in-game interface graphics from Blizzard's popular massively multiplayer game.
The suite incorporates technology from Stardock's Object Desktop in the form of Theme Manager OEM which has been previously licensed by companies such as Microsoft, Alienware, ATI, nVidia, Nintendo, and others to deliver branded desktops.
On a personal note, this is one of the best suites I've ever seen. And it's free.
