In a space-occupying video installation, Herwig Turk shows INVERSUM (2008), a work with a visual focus on states of approach and distance in the desolate environment of a salt desert. In the exhibition space, the viewers also get a haptic feel for the desert as several tons of salt turn the concrete floor into desert ground. Visitors plod across glaringly white, soft salt before they reach the projection screens. This way, attention is focused in an interesting way, and an emotional boundary emerges between the outlined desert area and the surrounding exhibition spaces. The viewers approach but experiences that approaching does not necessarily lead to closeness - a fact that is also reflected in the figure in one of the two videos played.
