'Thin Membrane' is a video installation with an immersive five-channel soundtrack. The installation consists of a built-in structure representing a part of a wall of a residential house. On the wall there is a window. The window acts as a frame for the video. The video shows what would be seen through the window; a group of friends having a nice dinner together. However, the dinner is occasionally interrupted by electric cuts, darkening the window. When the glass is darkened, a reflection of the viewer is seen on the window's glass surface, the thin film or membrane that separates the viewer from the people inside. The film is inspired by a short story about the theatrical rituals of an early 20th-century aristocratic family, from the book 'Berättelser om Natten' by Peter Høeg. 'Thin Membrane' transfers this setting to a contemporary petite bourgeois version, reducing the narrative to that of witnessing the ceremonies of creating togetherness, and perhaps otherness as a negative side effect of a 'positive' project.
