Lore artwork for download?


Hey guys,

I am new in the game (2 weeks now) and must say that the lore and game mechanics are pretty much fascinating and above all expectations. Since I play tons of Blizzard games for many years behind and am used to easily find artworks/wallpapers online, is there any chance to get some wallpapers with game artwork?

Ruul/Mordrake spells icons are top eye candies, at least for first 12 levels.
