Cool office decoration or the coolest office decoration? The statue was sculpted by the Weta Workshop in Australia, and shipped all the way into Irvine. No easy task, considering it's bronzed and 12 feet tall. Though from the pictures, it looks like it was installed in two separate pieces -- the wolf mount first, and then the Orc on top. And it also looks like Blizzard had a short unveiling ceremony, but it seems like it may have been just for employees from inside the building.
Bet that statue is more awesome than whatever's outside whatever building you're in right now. It's more awesome than what's outside mine, and I'm in Chicago.
