"I'm going to take a picture of my firstborn and use age progression
sofware to figure out what he'll look like when he's 16. Then I'm
going to frame the picture and keep it as a centerpeice in our house,
something he'll grow up looking at. Then when the appropriate time
comes, and he realizes that the picture is of him, I'm going to try
and convince him that he is a time traveller." Lifted from lamebook.
