Last night, many of us took a moment out to observe the Tribute in Light, the stunning light installation that marks the 9/11 attacks in a simple yet incredibly moving way way.

The project, designed by Julian Laverdiere and Paul Myoda, was initially commissioned by Creative Time six months after the attacks. Creative Time aptly describes the memorial as "an ethereal surrogate for the absent towers, the lights’ white luminescence not only replaces the void in New York’s skyline with a sense of memory and the possibility of hope and rebirth, but its ghostly presence is also a moving commemoration of the thousands of men and women who died on September 11, 2001."

Ever since then, the Tribute in Light has returned for at least one night every year.
