Dir. John Whitney, 16mm Color Sound 00:08:00
'In Permutations, each point moves at a different speed and moves in a direction independent according to natural laws' quite as valid as those of Pythagoras, while moving in their circular field. Their action produces a phenomenon more or less equivalent to the musical harmonies. When the points reach certain relationships (harmonic) numerical to other parameters of the equation, they form elementary figures."
