This series of numbered panes on the side of a Water St. office building is a clock. As a piece of architecture, it is intriging and looks more like a work of post-modern art than a serious, practical — if novel — way of keeping time. The historic Wall Street financial district of New York City is home to many examples of large-scale corporate-sponsored public art, most in the form of sculptural pieces in the foyers and plazas in front of office buildings.
