At the Portland Saturday Market the other day I happened across an interesting stall.
I poked my head in and found Sienna Morris, creator of images created with numbers...quite literally. Just as the pointillists used small daubs of paint to create coherent pictures, Morris uses numbers and calls the technique "numberism". She explained that the numbers she chooses to construct her drawings are significant; for example, in the piece called "A Cello", each string of the cello is drawn using the frequency for its particular pitch. The body of the cello contains the speed at which sound propagates through the particular type of wood. Even the 12th root of 2, which makes our modern musical scale possible, occurs in the image. Pretty cool!
