The Trade name for a device used by spiritualists, mediums and others trying to foretell the future. It consists of a large board with letters, numbers, symbols and a few simple words on it, plus a planchette with a pointer, resting on casters, which the communicator maneuvers until, by combinations of letters, it spells out answers to questions. The name is a blend of the French oui and the German ja. Since both words mean “yes”, it's apparent that the board will tell you pretty much what you want to hear.
