Public Art in Rittenhouse Square & Center City West

This glass-clad 58-story tower is one of the tallest 'green' buildings in the US. It's 140ft-tall atrium lobby is the location of Humanity in Motion, a beguiling work consisting of 10 horizontal poles criss-crossing the space on which life-sized figures balance like tightrope walkers. Chance are that your attention will first be grabbed by the mesmerizing series of high-res video images playing out on the 2000-sq-ft LED screen that is also here.

The 18-hour-long video never repeats itself and is never the same twice. Below ground level is a food court and shopping mall, which links directly to Suburban railway station.
