Here's an animation of the two memorial fountains at the World Trade Centre site in New York, which are due to open in three weeks time on the tenth anniversary of the 9/11 terrorist attacks.
Each waterfall will plunge 30 feet into a square basin then another 30 feet through a smaller hole in the middle, with the names of victims inscribed onto bronze plaques around the perimeter. The fountains are set in a paved plaza that's planted with 415 trees, all identical in size, beneath which a memorial museum is under construction.
The animation is by Los Angeles digital designers Squared Design Lab.
