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 awesome 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 on the left thumb and mana on the right.
In this video, you can see how it was put together -- amazing. I bet that having amazing nails like this makes you click your mouse button even faster.
