I just saw one of the neatest ideas I have ever seen. I think my little family is going to have to start doing this. A man named Diego Golberg in Argentina has been taking a photo of each member of his family on the 17 of July of each year (don't know why that date was picked, I figure the first one was when he thought of it). He posted the entire chronology as a webpage and it is pretty neat to see the changes. What a cool time capsule.
