Bioshock Easter Egg - See Jacks Face!

When you finish de-arming the lock on Andrew Ryan's door, you enter his office. Continue through the office until you get to the room with the words "Would You Kindly" written on the wall. Then walk up to the table underneath the writing and look carefully. You will see pictures taken from a security cam of the protagonist's face. You can tell because the character in the photos has the same sweater as you.
