Chicago's 820-feet-tall Aqua Tower is one of those buildings that make me dizzy. It looks like a vertical version of the stunning Lençóis Maranhenses, the sterile desert in the north of Brazil, full of turquoise fresh water ponds:
The architects, however, say that the Aqua Tower is inspired by the limestone outcroppings in the Great Lakes.
Whatever the inspiration was, the building is pretty. Not as pretty as the lençóis, but pretty enough. [Archdaily]
