I saw this today and think it is one of the coolest things I've seen in a while. This family in Argentina started taking photos of themselves back in 1976, when it was just the husband, Diego, and his wife. Then continued taking photos every year on the same day, June 17th, of every member of the family. It is so amazing and beautiful to watch the progression of these people as the years pass by. J. and I are definately starting this! See the whole progression up to 2007 here.
