Algorithm places September 11th victims next to friends at 9/11 Memorial

This year marks the 10th anniversary of the September 11th attacks. The brilliant memorial (partially shown above) to be unveiled that day is radical not only as a result of on-site electronics, but also thanks to a computer algorithm, responsible for resting fallen victims next to each other based on affiliation, not the alphabet. Victims will be grouped by employer, but also by their friendships -- before the towers fell, and now for generations to come.
