 Creative Time worked with the artist to realize the site-specific concept that emerged when he saw the rusted, disused mullions of the old factory, which metal and glass specialists Jaroff Design helped to prepare and reinstall.Finch was chosen to create the only work of art commissioned for the National September 11 Memorial & Museum.For his work, "Trying To Remember the Color of the Sky on That September Morning," Finch hand-painted 2,983 squares of Fabriano paper — one square in a unique shade of blue for every person killed in the September 11 attacks and in the 1993 bombing of the World Trade Center.
