Natural and built forces shape and shift the topographies of landscapes, urban environments, and human experiences. We locate our work at emerging edges of places in the making. There, we invent transmission devices and responsive practices that move with, change shape, frame light and sound, mark rhythms, and indicate direction and intensity of forces in play. The resulting topographical signals make the emergence of natural and built topographies material and palpable--and available for creative expression and making. They offer experiences of what cannot be grasped by words: namely, sensations of emergence ... the felt reality of being in relation.
