Make a scrap book with memories or something.
Make a collage[sp?] of pictures of his favorite things.
Anything really "random", but as long as you made it, or think he'll like will do, as long as it isn't some stupid thing that anyone could of got him.
Like something his friends wouldn't know to get him.
