The document discusses the 9/11 National Tribute Quilt, which was created in response to the attacks on the World Trade Center. The quilt contains 3,466 blocks made by people from across the United States and other countries, with each block dedicated to one of the victims. The central panels form an image of the twin towers against the New York City skyline. Each small block is considered a work of art representing an individual victim in an abstract form. Together the blocks create a powerful and moving image that evokes universal feelings of sadness and mourning while also representing hope.
