Here's a beautifully photographed collection of timelapse shots from Arizona and Utah, created by one man (Dustin Farrell) using one camera (a Canon 5D Mark II -- hey, it's only a few thousand bucks, why not pick one up?). It shows iconic locations, including many used in my favorite timelapse film, Koyaanisqatsi. But Koyaanisqatsi isn't available in 1080p, so for now this'll have to do. My favorite part: the Milky Way zooming by in the background. Well done, Mr. Farrell!
