Valentina Vuksic, born in Munich in 1974, studied media art and software development. She is currently working on her long-term project Tripping through runtime and conducting research for Hannes Rickli’s project computer signals at the Institute for Contemporary Art Research at the Zurich University of the Arts. Vuksic captures the electromagnetic emission of running laptops with inductive pick-ups and transforms the “runtime environment” of software into acoustic signals – thus revealing its electromagnetic footprint which can be heard as “computer music” inherent in the system. The basic hardware and software setup help determine whether we hear rhythms or erratic structures, spheric sounds or harsh noises. In this way, computer manufacturer, operating system, software and user all contribute to creating the composition.
