The perspective from the window towards a house and the reflection of this house in the window pane are framed in equal parts in the format of a video image. With the movement of the window pane the reflection of the house is repositioned on the glass surface. The space of the picture changes gradually, and new building constellations appear within the image detail.
By opening and closing the shutters that are installed in front of the window, different parts of the house are successively obscured and again released. Determined by the tempo of the engines of the shutters, the architectural space constantly changes also. All processes of opening and closing and the possibility of the reflection are combined to a sixty minute long sequence of image space- and perspective possibilities.
