In 2008, Clear Story designed and installed a synchronized lighting and media playback system for the newly-constructed Meadowcroft Rockshelter enclosure, designed by Pfaffman & Associates. A National Historic Landmark in Avella, Pennsylvania, Meadowcroft features a massive, 16,000 year-old rock overhang used by North America’s earliest human inhabitants. Clear Story worked with the project archaeologist to develop a narrative script, used when describing the historical and geological features of the site to visitors on the observation platform. The non-linear nature of this script demanded a truly interactive, user-controlled lighting system. The design intent was to integrate docent narration with lighting system control so that each feature was illuminated on cue as it was presented, directing the viewers’ attention throughout the experience.The project’s technical and logistical challenges required creative design solutions from Clear Story. For example, the lighting system was to be installed on a sloped ceiling of the enclosure building high above the renowned archaeological dig site. Equipment selection and installation, as well as access requirements, could not interfere with or disturb the working dig site.
