In this project, the first idea of group 12D is transportation technology. The Glasgow subway line is a loop, which lead us thinking about the regeneration of nature. We took some photos and videos of the subway and motorway and recorded some sounds. Our works include sculpture, video and sound. The video will be projected on the sculpture and forms shadow from different aspects. With the man-made sound and the sound of nature, we will finally present the works in the form of video, which is intended to reflect the cycle of life, death and rebirth.
