Cassandra

Cassandra displays a small, unobtrusive floating window with a random fortune. It picks a file from any Unix fortune or bongo-bob style files in the "Fortunes" folder within the preferences folder. No sounds. No dialogs. Just your fortune. It is an application, based on Matt Slot's time-tested appe Windows code, which means no conflicts. Just stick it in your startup items and have a chuckle whenever you turn on your mac.
