Explorative diagramming of the Rhine river in which a hybrid topography was created by merging the first parallel projection of the Rhine (the 'Rheinpanorama' created by F. Delkeskamp in 1811) with audio data extracted from the opening scene of Richard Wagners' "Rheingold" opera. Audio data was extracted at a 1000ms interval via a custom program which later transformed the extracted data into sectional geometry in AutoLISP.
