Last night, you may have seen the Tribute in Light beams. The September 11 light installation, which involves 88 separate lights, was being tested ahead of its official annual lighting next week. We're checking to see if the location is the same as last year (West and Morris Streets), but they are visible throughout lower Manhattan and Brooklyn. On Friday, September 11, the lights will on at sunset and will "fade away" at dawn on September 12. The Tribute in Light was designed by artists Julian LaVerdiere and Paul Myoda, architects John Bennett and Gustavo Bonevardi of PROUN Space Studio, architect Richard Nash Gould, and lighting designer Paul Marantz and produced by the Municipal Art Society and Creative Time—it was first seen in March 2002 for a month and then became part of the September 11 anniversary fabric. In 2002, Bonevardi wrote about project, "We're not reconstructing the towers in their original size, but the distance between the two squares of light is the same as the distance between the actual towers. So in effect, we're not rebuilding the towers themselves, but the void between them."
