The pools have fountains of "dandelion" sprays, which are turned off every day just before the times the Twin Towers were attacked and stay off until 10:28 when the last Tower collapsed. During this period on 9/11, the sun passes over the Grandstands and onto the pools of water with 2,792 aluminum Diamond Monuments, one for every victim, that reflect back the sunbeams to the Grandstands. The diamond shaped faces of the Monuments, with names of all the lost souls, are cast from the aluminum from the fallen Towers, each about four foot tall, and are buffed and focused to distribute reflected light across the entire Grandstands. Most of the Monuments are silver aluminum, but among them are some with warm reddish copper, white-like stainless steel and blue anodized aluminum surfaces, (of red, white and blue) representing the fallen uniformed heroes lost on that fateful day.

As the sun sweeps across the morning sky, spectators will experience the Diamond Monuments in both locations slowly reflect back groups of sunbeams in unison, each group sparkling briefly to life for about 15 minutes, rising up like a flock of birds taking flight. The public spectators in the Grandstands may interact by waving and casting shadows, creating a lyrical connection with the victims.
