One interactive exhibit that has inspired me is the Miniature Railroad exhibit at the Carnegie Science Center. One aspect of the model that I enjoy is the combination of the tactile and technological. While this display is relatively simple in comparison to others in the museum, the combination of physical objects and technology to invoke movement and life in the Pennsylvania replica is exciting to me. Two years ago, the exhibit had its centennial, encouraging visitors to remember the advances in model building and interactivity that the museum has achieved. The exhibit operates with a series of buttons and screens, which are updated by technicians and craftsmen alongside the physical model every fall. The museum commits to preserving the past while upholding modern standards of technological advancement.
