Take a baggie, tie a few overhand knots in it, hang it up over some water in a dark room and set fire to the bottom. It will gradually burn and melt. The flaming drops go wheep as they fall, and their fiery trail is striped horizontally by the sound vibration. That’s down-home cymatics.
Painter Hans Jenny, influenced by Rudolf Steiner, has been playing with other vibration display techniques—sand on iron plate, glycerine on membrane, lycopodium powder, iron filings in magnetic field, crystallizing salt, mercury drops, and viscous liquid. The result is a spectacular book of photographs of the shapes that periodicity can take in three dimensions.
[Stewart Brand, Whole Earth Catalog Fall 1969, p.9]
