This work was created on the invitation of the city of Sønderborg. You'll see two interlocking frames that provide space to view the landscape behind and around you. The shape of the two lines depicts the border lines between Denmark and Germany before 1920 and since the peaceful border shift at that time. A borderline, if it is an open border, is only a transition from landscapes that are only marked on the map. If you move freely in nature, in the landscape, the visible horizon shifts further and further through your own movement. In this experience, the horizon line becomes a natural border, which arouses curiosity as to how things will go beyond it.
