What are some really clever gifts to personalize?

I want to get my boyfriend a personalized gift for his birthday. Not monogrammed, but maybe something I can put a picture on, or his full first name (possibly last).
I don’t want to get him a (beer) mug, a blanket, watch/jewelry box, or photo album
I want to get him something really clever. I saw pillow cases I though would be cute, but I don’t know how how great of a gift that would be for a guy.
