The the embroided image depicts a forest in the german region called Harz. This particular  spot is famous for its echoes. The image was shown in an exhibition about 150km away from this place. The shoutings of the visitors in the exhibition space were transmitted into the valley through an online streaming service and loudspeakers. The responding echo near the forest was captured by a microphone and streamed back into the exhibition and played through speakers behind the image.
