Thin Membrane 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. The viewer can follow the dinner, its different rituals, objects, and other symbols which create a sense of togetherness and are highlighted when the dialogue cannot be heard. At times, the viewer can hear laughter through the window, but otherwise the soundtrack consists of the sound of a hard wind. The dinner is occasionally disrupted by electric cuts. The window glass is darkened, revealing the reflection of the visitor, the outsider, separated from the party only by a thin glass membrane. The video installation includes an immersive five-channel soundtrack.
