One of the coolest things about Diablo III is the amazing art direction. Evidenced in all this rockin' original art, it's one of the things that sets the game apart from its many imitators.
This terrific Diablo III nail art by DeviantArtist Undomiele really takes the cake—it's got recreations of two of the more famous pieces of concept art along the fingernails with
health mana on the left thumb and mana health on the right. (Sorry, reverse images are confuuusing.)
In this video, you can see how it was put together—very cool. I bet that having amazing nails like this makes you click your mouse button even faster.
