Signals embodied in physical form are — ahem — transubstantiated into ephemeral epiphenomena carried upon timestreams; an abstraction in form becomes concrete in perception through its dissolution. A wavy groove etched in vinyl becomes sound. A magnetic fluxuation on a band of plastic painted with a layer of rust particles becomes sound or a moving image or both. A linear sequence of numbers becomes an array of color or lightness/darkeness values yeilding an image or even a moving image or even a talking one.
