This woodcut painting is derived from SUN Xun’s animation work “Time Spy”. The film combines the traditional woodcut and 3D visual experience and discusses the relationship between the time and life. We preserve the past by maintaining our memory and value the future by our desire. When we mention history, present, future, and eternality, memory could lie to us and tomorrow could never exist. There is nothing forever because we only live at the moment. Everything endures in the flux of time. The Universe is the only authority that could determine everything, and we are just the spies of time.
