The unspeakable openness of things

A large ring seems to cross the boundary between physical space of the room and the room’s reflection in a vast mirror that covers the ceiling. The light emitted by the ring, produced by monofrequency lamps, reduces all colours to a range of yellowish grey tones that sharpens viewers’ visual perception. These lights, often used to illuminate tunnels for enhanced safety, appear in many of Eliasson’s works, including The weather project at Tate Modern, London, in 2003.
