In the centre of the room there is a square platform raised just a few centimetres from the ground which beckons visitors to enter. The platform is brightly lit and almost impercep­tibly lined with the pixel structure of a video projection image. If two or more people enter this area at one and the same time a structure is created by lines projected from above. The shape and path of these lines vary and change constantly. The division and size of the core cells allotted to the protagonists alter depending on the conduct and movements of the visitors. What this interactive installation clearly attempts to demon­ strate is the relationship between the individual and the group/community or, to be more precise, society. Each of the lines of light constitutes a personal area, which is invisible in our daily round of activities and yet has a massive influence on the way we behave and communicate. A simple linguistic example is provided by the phrase: to get too close to somebody, to get on their nerves, which indicates that somebody has gone too far in physical or psychological terms. Then there are the so-called Voronoic diagrams as a metaphor for the duality of a wide variety of relationship parameters in all major fields, e.g. in biology the dominance pattern of flora and fauna, in chemistry the attribution of atoms to crystalline structures, the geological impact of the forces of gravity in space, intelligent control mechanisms for robot-operated production lines and psychological sales strategies in supermarkets.
