When I graduated from college, one of my Bridge friends showed me a neat alternative to a yearbook: use a deck of cards and fine-point Sharpies. Have your friends sign and decorate the cards. Part of the fun is seeing what cards people pick. We found a tendency for guys to pick black suits and girls red; close friends want aces and face cards, and people with a lot to say want low spot cards for their large empty spaces. High spot cards were in the least demand.

This would also work for an ordinary yearbook, leaving summer camp or an internship, or whatever.
