In case it slipped under your radar, the Caldeum page on the official Diablo 3 site was recently updated. On it, you will find some nice new animations atop the page (I'm digging those waterfalls in the background) along with some city guards who, according to Bashiok, "don't appear to be taking their jobs too seriously." Hey, everybody needs to take a break from the day to day grind every now 'n then, right? Actually, you see those giant bones? I'm thinking the two guards just overindulged themselves for lunch and they're just taking a little breather before getting back to work.
The superbly atmospheric music on the page by Russell Brower (aka: King Theoden) is definitely worth taking a listen to, so be sure to check it out with your speakers turned on.
