With the massive number of players logging in every day to WoW, there's an equally expansive amount of art and media coming from that player base. Very few games have ever brought out such a community of creative minds showing the rest of us their vision of a fantasy world. From machinima to custom WoW dolls (I mean action figures -- right, guys?), to Horde/Alliance-themed cakes, there are a ton of different venues for artists of all varieties to express their passion for the game.
I've just recently begun to start watching WoW-based machinima and have discovered there are quite a few masterpieces out there from people who seem talented enough to write or direct feature films. After the Cataclysm launch, I'm going to start an ongoing fan fiction story about a rogue and what his life is like after Deathwing ravages Azeroth. It should be plum full of adventures and high jinks! Although I'd love to include custom artwork with that story, my drawing skill ends at stick figures, so I'll have to use to screen shots.
Out of all the different art, videos, and other "warcrafts," are there any you'd like to participate in? Or maybe you already check out great fan art, make custom troll outfits for cosplay, or bake cupcakes shaped like murlocs. What are your favorites?
