Der Offene Schaltkreis (open circuit)  

A sound installation by Christoph Haag, Martin Rumori, Franziska Windisch and Ludwig Zeller.

A silent labyrinth created out of open copper trails on the floor carries the electrical signals of a multichannel sound repository. By putting wireless speaker- cylinders on them, the carried sound layers can become audible and the interpretation by the visitors gets possible. The "Offener Schaltkreis" reacts depending on the manner in which the speakers are used: If nothing is moved, the sounds stay calm and soft, but as soon as a single cylinder is placed elsewhere, the sounds of all speakers intensify simultaneously. This results in a dynamic relation between silence and noise, which is influenced by the visitors.

"L’Oeuvre ouverte | PureData Convention 07 brings together artists, developers and theoreticians who develop, use and reflect on PureData. It acknowledges the broad range of artistic disciplines that make use of the software and addresses questions of openness and accessibility. It provides a theoretical context for the understanding of media art practices that engage in the aesthetics and politics of Free Open Source Software Culture."


"The Linux Audio Conference is both a meeting of developers writing audio software for Linux as it is a music festival, where artists from all over the world show how free software can create fresh and exciting new sounds."

Paper Circuits  

A sound installation by Christoph Haag, Martin Rumori, Franziska Windisch and Ludwig Zeller.

Paper circuits is a sound installation consisting of five loudspeakers, each one covered with a pile of papersheets. With a prepared pencil one can create his own visual as well as sonic composition. By drawing on the paper and placing audio contacts on different locations of the graphite tracks the loudspeaker underneath will start so sound. Each visitor will build his individual configuration and create continuously new sound collages and associations out of a repository that carries sonic references to utopian movies, novels and scientific texts on societal ideas.
