Duallinien was seen as a guest installation at the Distortion Festival 2017 in Copenhagen. The entrance consisted of discarded sea containers spanning 10 km of white rope. During the day, the sun played its play of light and shadow - at night, the interactive installation came alive: the ropes illuminated from below were played by the pouring people and their shadows. Only at second glance the visitors noticed their influence on the installation. As a temporary architecture, the installation was used as a dance floor and chill-out area.
