Turnstile, an artwork installed at Schadowstraße underground station in Dusseldorf, selected in conjunction with a competition to artistically enhance the city’s Wehrhahn line.

Turnstile is designed as a snapshot of a location comprising pedestrians crossing the square above the underground station, a video camera observing the pedestrians, lifts transporting passengers to their platform, an LED wall situated above the rail lines at the front of the station plus 23 screens showing a birds-eye view of Dusseldorf interpreted as generated patterns.

The generative video on the front wall of Schadowstraße underground station captures the movements of pedestrians above ground and custom-made software interprets these movements as ‘energy sources’ or ‘virtual fuel’; consequently the temporal-spatial accumulation of events unfolding above the underground station is manifest on the screens installed on the station’s LED wall—ultimately becoming a virtual interpretation of the location’s lively hustle and bustle, modelled with the help of artificial intelligence. Small, virtual beings use the motion-energies to build a temporary, fluctuating architecture that ebbs and flows in accordance with the stream of passers-by. The artwork encompasses urban space and its geometries. Geometries define the earth up to a point; when humans settled, geometries were also used to map the near and far, the inside and outside, the you and I. In short: geometries map the physical coexistence of human beings.

Geometry orders habitats. It interprets, structures, and alters movement within a space; it is a component of the ‘language’ of habitats. It records the flow of movement, the swarm behaviour of humans within urban environments and the surrounding areas.

Our software follows a particular grammar: the interplay of local events, pedestrian activity, and social interaction becomes architecture. The diverse possibilities of the algorithmic performance soften the radical position geometry naturally holds and instead pose a hypotheses and make an offer to the citizen; an architecture that is formed from the actions of the passer-by. This is how the software builds an artificial intelligence on the basis of the geometric logic of an individual artistic approach.

Ursula Damm (DE)

Ursula Damm (DE) started as a sculptor with models of space and time, developed in a bodily experience. In the 1990s installations became geometric processes of settlement patterns. Since 1995 her installations respond interactively to architectural aspects with video tracking technology. Aside she developed numerous installations dealing with nature, science, and environmental issues. Since 2008 she holds the chair for Media Environments at Bauhaus University in Weimar, where she established a DIY Biolab and the Performance Platform at the Digital Bauhaus Lab.
