Long time Pittsburghers will remember the animated sign that lit up the WESCO (Westinghouse Electric Supply Company) building on the North Side for 30 years before it was demolished in 1998 to make way for PNC Park.
During the day, the sign was nine static images of the iconic Westinghouse logo in a row.
But at night, the sign came alive! Click on the image below and enjoy the dance.
