...I'd say so. MGM Grand

The first site I saw like this - where the viewer is immersed in a photo-heavy environment - was a Vodaphone site a couple years ago. Since then there have been several notable ones, but this site has great scene transitions and video with a lot of cool after effects. 

They've used a conventional navigation menu in addition to the clock-like one to improve usability, but it seems if the clock-like one was better designed they could have gotten by with just that interface alone.
