Strukt Portfolio: Interactive Installations


Interactive light sculpture

Art project for sound:frame festival at Kunsthalle Wien

The interactive audio-visual installation Lightrails was created by Strukt together with unheilbar architektur for Project Space inside the Kunsthalle Wien, commissioned by sound:frame Festival.

Lightrails is a light sculpture with the intention to redefine and reinterpret the exhibition room. A simple but effective mapping technique was used to create seamless projections on both sides of the object. Light-beams were triggered by the visitors and ran through the room, following the surface created by the sculpture. Each reflection of the light-beam was accompanied by a sound effect. The speed and brightness of the beam was directly influenced by the force the visitors used when triggering the beam stepping on pedals on the floor. This also influenced the volume of the sound effects. The audio signal was played back on a surround sound system that allowed a spatial positioning of the sounds and created a truly immersive experience.

The sound design was courtesy of Digitalofen Audiobakery, which also created the ambient sounds that were pervasive through the room. The real-time multipurpose toolkit vvvv was used to create the installation. The projectors were provided by concept solutions. The construction of the sculpture was kindly supported by INDAT and the whole project was hosted by the sound:frame Festival and financed by departure.

Thanks to all of the mentioned organizations and all the individuals who helped us to realize this project.

The new home for the lightrails is the Viennese club “Pratersauna” where it is illuminating one of the dance floors:
