Sarah Oppenheimer creates installations that make the viewer question the physical space. She obscures and transforms ordinary rooms into spaces that manipulate the viewer’s perception of the physical space. She cuts angled holes in the walls to abstract the corners, making them seem like they could open like an accordion while waking through them. Visitors have even reported cases of vertigo. Although it is possible to walk through the holes, it still requires you to be very aware of your movements.
The lighting in the room plays an important role in contributing to the overall feeling. Oppenheimer adjusts the lighting according to what the predicted temperature of light in each room will be, and adjusts the illumination so that the solid painted white walls contain various tints. From a distance, the corners almost appear as abstract flat surfaces.
