Oracle of Chemnitz reanimates garage relics with interactive rotary phone
Old rotary phone install rings to life, sharing tales of garage artifacts with 2,700 visitors
The Oracle of Chemnitz is an interactive art installation born from the School of Garage, a participatory project during Chemnitz's tenure as European Capital of Culture 2025. Researchers Karola Köpferl and Albrecht Kurze repurposed a HackLab garage into a space where vintage objects—a typewriter, radio, desk, tires, mixer, and a rotary-dial telephone—were each given names, personalities, and stories. The centerpiece is the rotary phone, which rings as visitors approach. When answered, it asks for the visitor's name and month of birth, then weaves a personalized narrative about one of the devices, along with suggestions to explore related locations around the city.
The installation runs on a custom-designed system that tracks proximity and triggers the phone's ring, turning a mundane interaction into a connection with local history. Built in just one week, the project demonstrates how minimal technology can create meaningful public engagement. Over three months, approximately 2,700 visitors interacted with the system, each leaving with a unique story tied to Chemnitz's industrial past. The project was presented at the ThingsCon State of Responsible Technology 2026 conference and is detailed in a paper on arXiv (arXiv:2608.17407) under the Human-Computer Interaction category, showcasing how participatory design can bridge generations and reanimate forgotten objects.
