Not sure if everyone has heard of project 365. Essentially, rich people who have time to contemplate (i.e. blog) and access to digital cameras take a picture of them selves, everyday for an entire year. I'm kinda being sarcastic here, but it's a novel idea which people have approached differently and produced a variety of results. The above picture is of Noah K. Everyday with some celebrities at some VH-1 award show (flickr Set of all celebs). You can watch his YouTube compilation here.
The point here is that living in this "digital" world makes this type of "personal documentary possible"; you can see how you age and how you change over time. Noah has a pretty good poker face, after you see the YouTube video you'll know what I mean. So who's down for a 365 project?
