Excogitate The Life: Artist created a literal 'face book' by taking his picture daily

When artist Jonathan Keller spent the last of his money on a fancy digital camera in 1998, his girlfriend at the time wasn't pleased. When she demanded to know if he intended to use it every day, his answer was a defiant one. However, the only thing he could think to photograph on a daily basis was himself. Sitting at home in his bedroom he took a snapshot of his face. The next day, he took another.
