While visiting New York, I managed to take a look at the designs for the World Trade Center memorial displayed at the Winter Garden at the World Financial Center. I was attracted to this design, which is now the finalist in the competition.
The design is both evocative and strangely haunting. It reminded me of the simplicity of the Vietnam Memorial in DC, both simple yet someone deeply poignant. Some of the other designs submitted were intriguing, but many were either unfeasible or maudlin. This design seems to strike the right balance to me, not trying to oversell the human tragedy of the event but serving as a space for reflection and remembrance.
