Ethereally Impacting

"There are vibrations which the ear cannot detect, so slow as to make no audible sound, but there are contrivances by which they can be made visible to the eye. When sand is thrown upon a thin metal disc, to which a chord is attached and caused to vibrate, the sand will immediately arrange itself in a perfect geometrical pattern. The pattern will vary with the number of the vibrations. These are called "Chladni's figures." Moist plaster on glass or moist water-colour on rigid surfaces will vibrate at the sound, say, of the human voice, or of a cornet, and will assume forms of various kinds—geometrical, vegetable and floral; some resembling ferns, others resembling leaves and shells, according to the pitch of the note."
