Woah, very cool. Although I think I'm more interested in the time lapse motions of large ocean going vessels than the tilt shift trick... which I think isn't always appropriate to moving scenes, when an object moves between the in focus and out of focus region sometimes it ruins the effect to me.
Several notes. It appears that those videos were done with an actual tilt shift lens. I'm not 100% certain of this, but in the comments the creator of the video says he "focuses with a lens, not with software" or something to that effect. Which then suggests that this video was made with a tremendous sequence of still images rather than a video camera.
Also, and only peripherally related to this.. that site can host HD video! This is huge to me. I clearly need to check out the full spectrum of video hosting sites, I'm too used to the ultra low quality youtube which has at the same time become the standard.
