The audiovisual installation stromlinien can be regarded as an acoustic interpretation of visual patterns. Through several video projections, a grid of luminescent lines is disseminated into the exhibition space while at the same time being translated into 'acoustic lines'. When regarded as a graphic score, each of these lines gets interpreted as a frequency and time envelope, microtonal shifts fluctuating between 50-60Hz. As acoustic source material served the audio recording of a 50 Hertz signal tone, which is also the power frequency of the European electricity network.

stromlinien is based on photographs taken at the Green Mountain (Jebel Akhdar) in Oman which show one to six wires, in front of the cloudless Omani sky. Thinner lines result in higher octaves, brighter lines in brighter sound color. Through the overlap of concurrent visual layers, a continuous sound- and image composition is created. Sound progressions, pulsations and interferences can be partially tracked on the visual layer, although sometimes they dissolve within the complexity of sound clusters.
