Olafur Eliasson creates works that question our perception of reality and relationship to nature. He often uses experiments and technology, in the form of light installations, to investigate how we perceive colors and react emotionally to them. Double double Hung Windows provokes an optical effect by the overlapping images of windows on a flat wall projected by two theatrical lights. This work reflects on our capacity to perceive spatial depth physically but also metaphorically. As the artist has said: “A window always works like a picture frame: like a picture of a picture of a picture. There are different levels of representation that stack up and we have to be aware of this.”
