“Land art from the 1960s and 1970s exists in remote locations. I was interested in creating something very urban,” Aitken says. Mirror is a large LED screen, wrapped around the corner of the museum, with thin strips of vertical lights. Aitken has been filming for the project over the past five years, capturing images of central Seattle as well as the surrounding area, “from the Pacific Coast to the Cascade Mountains”, he says. A computer programme will select which parts of the footage to project in response to a live feed of information that will range from the weather to the density of traffic in the streets of Seattle.
