A co-worker turned me on to Nicholas Felton. He does "annual reports" on his life each year. Now I can't imagine how organized one would have to be to do this, but the end result is pretty impressive. Nicholas tracks everything, and I mean everything. Travel, food intake, people talked to, etc. Then, when he has everything compiled he created some stunning visuals to go along with the data. Here is his report from 2007 as an example.
