I've long been an admirer of the Japanese renga, a collaborative poetic form. One of the major drawbacks, however, is trying to remember the rules. Each person participating must write a two- or three-line stanza using a pre-determined subject, usually a season of the year. In an autumn renga, shown here, the first writer begins with a three-line verse about autumn. The next writer completes a two-line verse about the moon, which is usually related to autumn.

The game board above really nicely condenses these rules. Even though this was just a simple assignment, it solved a long-standing problem for me.
