The Aon building, in downtown Chicago, has a variety of waterfalls and fountains. This black and white photograph, taken in September 2012, is a portion of the veritable labyrinth of water in motion and its corresponding intricacies, changing moment by moment.
Specifically, as I remember, one of the entrances to the Aon complex was directly off Randolph Street and led down, via staircase or elevator, to the courtyard below, which, itself, has a beautiful fountain.
On either side of the stairway/elevator are two waterfalls which begin very near street level and fall to the courtyard area below.
