Student Art Contest charged students to come up with a piece of 3D art that fit into the Warcraft universe but was wholly new and unlike anything the art team had seen before. Now, we finally have the winners of the contest, and as Kotaku pointed out, they basically made their own little worlds here.
You should definitely head to the official site and check out the winners. Each of the grand prize winners gets some actual mentoring from a member of the Blizzard World of Warcraft art team. Can you imagine that? That's amazing. Man, where's my time machine -- oh, and some artistic talent, I'd need that too. This is some amazing work.
