Border Tuner is a large-scale participatory art installation. It is designed to interconnect El Paso and Ciudad Juarez and to highlight the complex and long-term collaboration that exists between the two cities and the two countries, providing a powerful and positive counter-narrative to the current rhetoric over the border. The piece was installed between Mexico and the United States, where powerful robotic reflectors create bridges of light that open live sound channels for communication across the border. The piece creates a fluid canopy of visible light for up to 10 miles. Visitors can move the lights in six interactive stations, three located in Chamizal de Juarez Park and three at Bowie High School in El Paso. Each of the interactive stations features a custom-made music stand with a microphone, a speaker and a large knob or dial. When a participant turns the dial; Three nearby reflectors create an arm of light that follows the movement of the dial, automatically scanning the horizon. When two of those arms of light meet in the sky and intersect, a sound channel opens between people in the two remote stations. While they talk and listen, the brightness of the light bridge is modulated in synchronization, a flash like a twinkle of the Morse code. Each interactive station can tune in to any other station, so, for example, a participant in Mexico can connect to the three US-based stations. UU. or the other two in Mexico, as desired.
