The train moves fast through the tunnel while roaming inside one flower after another. The film combines the footage of the subway tunnels and the still photographs of flowers, allowing them to interact. Watching this film is like embarking on a psychedelic cosmic journey. In fast motion, particles of various colors rush towards the viewer. The screen is like a black hole, as if there is a gravity sucking the audience into the tunnel. The audience seems to experience passing through clusters of colorful nebulae, and also like crossing through a microscopic world. The flowers in the background are from still images made by the director. The sound of Flower Tunnel uses Shepard tone, to make an unworldly effect of perpetual motion.
