Time lapse is hot, time lapse mining via Google is amazing, particularly in terms of viewing how time impacts nature, climate and the environment.
This technique is awesome because it allows us to view years upon years worth of change in a matter of seconds. There are a multitude of uses here, mostly relating to scientific study of nature and climate, but it's hard to deny that it's an aesthetically pleasing effect. Of course, this has been accomplished before (and at a higher quality) by determined and disciplined photographers, but this technology could vastly expand our ability to witness subtle changes in place and natural phenomena that would otherwise go unnoticed.
Google's Siggraph PDF show how this tech works. Pretty astounding to say the least.
