One of the features that I love most about my new Canon 60D camera is the built-in tilt shift feature in creative mode. It is really cool to miniaturize scenes. I need to play around with a bit more because these were my first attempts at figuring out which images process well.
Here is an amazing video done with tilt shift: http://vimeo.com/15596222
