i wrote a java applet to make a text file of pixel RGB values for any picture, with the dimensions as a "header". then in supercollider i read the file in and parsed the data into an array of brightness values for every horizontal row in the image. then i wrote a routine to read through those arrays, top to bottom, where each pixel's brightness corresponds to amplitude, and x-position corresponds to frequency along a 12tet gamut. in this piece, each row lasts for 4 seconds, with 50% overlap, and a von hann window. expect this to reappear with different gamuts, waveforms and time-grids.
