Italian manufacturer Space Cannon, supplier of the 88, 7000W luminaires that form the twin beams of the September 11 memorial 'Tribute in Light,' invited A|L for a preview during the focusing process. The magazine presents these images to an industry that should be proud of its chosen medium. In its third year, the memorial again proves the immense power of light, and its complex ability to heal, awe, memorialize and haunt.
