In the interplay of different art forms (puppet theatre, music, dance, visual arts...) the artists in Echtzeitkunstwelt explore the possibilities of performance and liveness in digital space - always adapted to the specific site. For ORF musikprotokoll, Dominik Grünbühel, Norbert Unfug and Sebastian Pirch expand their real-time art world and build a walk-in musical instrument in VR at esc medien kunst labor. Sounds, beats and samples are physically manipulated with virtual objects and create a choreography: interactively, individually or collectively. Visitors can influence the course of the choreography by looking or moving around the room. Knobs that extend throughout the room and buttons that require full physical engagement make making music a physical experience. The online multiplayer function allows people from all over the world to participate.
