The Comcast Experience is a 25.4 feet (7.7 m) tall, 83.3 feet (25.4 m) wide, 2,000 square feet (190 m2) high-definition LED screen situated on a wall in the winter garden. The screen is composed of 6,771 Barco NX-4 LED modules. The installation, designed and produced by Niles Creative Group, premiered on June 6, 2008, and runs eighteen hours each day. The content of the video includes panoramic views of Philadelphia historic sites, images of space, dancers, acrobats and actors moving around a background designed to mimic wood paneling of the walls of the lobby. Another part of the installation displays images of cranes and machinery forming into a clock which tells the correct time of day.
