A must do in New York City. Views from the observatory are amazing. The offer iPads for 15 dollars which match the views from the windows. You click on North, south, East or west to march the direction and it shows you an overview with links on each landmark in view. You click on the link and you get a flyover to the landmark and a 30 sec to 1 min overview with the background story of the landmark. I thought it was great and really well done.
