Thinking about how to represent sound visually - I love the plotted linear image, but maybe a bit too obvious? - I was thinking about piercing paper to represent the peaks and troughs and this reminded me of braille. It seems that the immediate mental connection to braille is touch - the sensation of running fingers over the surface. It also made me think about erosion - some form of tactile work which invites touch and then wears away as it is stroked over a period of time?
