|CUT UP MACHINE|
Throughout the ages, men have attempted to foretell the future by casting stones, or coins, or dice, or sticks. By observing the effects of decisions made by an extra human agency, that force which determined the fall of the dice, chance, fate, karma, the Tao, it was felt that the workings of the universe itself could be observed. The invisible could be inferred by its effects upon the visible, a feather launched into the wind, a stick cast into a river.
Although the results of these fortune-telling experiments can be fascinating and even educational, especially when applied to the arts, their true importance lies in the attempt by the experimenter to understand the universe, its purpose and his own relation to it.
