My current wall paper is Liam, my cousin's baby son. James, my cousin, is a young father, and he's totally being the overactive parent. We get a CD full of photos every holiday- Liam in a pumpkin suit, Liam under the christmas tree, and most recently, Liam with little cherub wings.
My computer does not have a screensaver, but it does have a background of Jesus holding a child and looking up towards the child's mother and smiling at her and her smiling back... which I can't bring myself to take down even for the awesome secret cover art for the IKCG, but if something was to replace it... it would probably be the IK cover art b/c it is sweeeet!
