You may have noticed it over the weekend: All sides of the Kennedy Center lit in cobalt blue and acid green.
That light show, it turns out, was just a test. But last night, as the Kennedy Center celebrated the opening of the month-long Nordic Cool festival, the building officially flicked on "Northern Lights," the massive display that was created solely for the festival.
Mimicking the Aurora Borealis, the project was created by Danish lighting designer Jesper Kongshaug, whose work also includes lighting in the Copenhagen airport and an award-winning design at the Royal Danish Playhouse.
The lights will swirl nightly between 5:30 and 11 p.m. through March 17.
