It looks pretty much the same as it did 9 years ago: a great big gaping hole in the middle of Lower Manhattan. However, currently (July 2010) the frame of the new tower ("Freedom Tower") is being constructed. See the first Related Link below a Ground Zero webcam, showing what Ground Zero looks like today. The second Related link is the official website for Freedom Tower.
