Each of the interactive “Border Tuner” stations features a microphone, a speaker and a large wheel or dial. As a participant turns the dial, three nearby searchlights create an “arm” of light that follows the movement of the dial, automatically scanning the horizon. When two such “arms of light” meet in the sky and intersect, automatically a bidirectional channel of sound is opened between the people at the two remote stations. As they speak and hear each other, the brightness of the “light bridge” modulates in sync, —a glimmer similar to a Morse code scintillation. Every interactive station can tune any other, so for example a participant in Mexico can connect to the three US-based stations or to the other two in Mexico, as they wish.

“Border Tuner” is not only designed to create new connections between the communities on both sides of the border, but to make visible the relationships that are already in place: magnifying existing relationships, conversations and culture. The piece is intended as a visible “switchboard” of communication where people can self-represent. The project seeks to provide a platform for a wide-range of local voices and an opportunity to draw international attention to the co-existence and interdependence between the sister cities that create the largest bi-national metropolitan area in the western hemisphere.
