Ze Frank's new Color Wars series of online competitions has a contest called Young Me, Now Me where you try and recreate a photo from your youth now. I was just visiting my family in Austin and dad showed me some old photos he had just scanned. So here's me in 1972, sitting in my Grandpa's old Model A on the farm in Iowa. And me in 2008 sitting in my parents' Toyota in their front driveway.
Update: I'm a winner, in the category of "Most Changed in Appearance".
