The first solo exhibition of the New York based artist Sarah Oppenheimer at Duve Berlin presents P21 x P41, two installations with periscope like structures. P41, for example, allows the viewer to peer into the private office area of the gallery. Two holes in a wall, one above the other, allow having two lines of sight simultaneously from any given position. The hole with the periscope doubles the image and inverts it, so that the viewer sees the bottom half of the body above the top half of the body. In this interview with Sabine Trieloff, Sarah Oppenheimer talks about her installations at Duve Berlin. Sarah Oppenheimer: P21 x P41 at Duve Berlin, October 30, 2008. Interview and Opening reception.
