The audio-visual installation consists of four interacting bar-code scanners. They respond to the movement of the people inside the exhibition space through the specific 'beep' sounds and flashing scan lights.
The bar-code scanners moved by motors register their surrounding constantly. The flashing lights create abstract structures of crossing lines on the walls. At the same time the visitors' shadows become visible as they stand between the scanners and the projection wall. This way the visitor becomes part of the projection.
The installation on the one hand is inspired by a trivial machine from the consumer world we all know from our every day life. But in fact we know them but even do not recognize them. On the other hand the scanners focussed on the visitors remind of security cameras which control parts of our life even if we do not believe they do. Which information are recognized and stored by the scanners when we buy something?
