If you're in New York City tomorrow, stop by the South Street Seaport around 10 a.m. to see the launch of The New York City Waterfalls.

The art work, created by Olafur Eliasson, consists of four falls, all of which are on the East River and visible from the South Street Seaport. Perhaps the most dramatic is the one under the Brooklyn Bridge (artist's rendering left).

Sort of like Chicago's Cloud Gate sculpture, this is one of those art works that makes you wonder: How come nobody thought of this before?

The waterfalls will be up through Oct. 13.
