An openly arranged installation of circles in different sizes are displayed next to each other on a wall. In this system of arrangement an abstract of a spatial situation is created with the notion of an imagined movement, reminding of models of planets, or of a planetarium. This impression is supported by the circles´ divison into two zones of light intensity, this image has been stored by the viewers memory as a day/ night schedule of celestial bodies. Also, semicircles are installed on the floor, and associations of horizons arise.
