In the early Sixties, a Swiss scientist named Hans Jenny experimented with the effects of sound vibrations on fluids, powders and liquid paste. Photographs of Jenny's work were as remarkable as his observations of the patterns which emerged. He wrote of "powder erupting into clouds" and crypts like honeycombs; pillar like prominences; column waves and wave forms; current storms and storm currents.
He concluded, "However, this is not an unregulated chaos; it is a dynamic but ordered pattern."
