A variation: Again, a large group of different items (I was thinking abstract images of colors and shapes, but toys is a good idea too) is visible to the group. One of the objects is selected and then each person writes a description that selects that object alone out of the set. The goal is to write the shortest description that can pick that particular object. Once everyone is done, answers are compared, and violations are sought: if one of the other objects fulfills all the requirements of someone's description, they are disqualified. Whoever has the shortest description that describes the chosen object and only the chosen object wins a point, and the game is repeated with another object.
