Artist Song Ting applies adversarial generative neural network algorithms to complement the color of Dunhuang murals. To make up for the millennium of irreversible time, and the humanistic geo-nostalgia brought by physical isolation. Perhaps the tens of millions of human food, clothing, housing, and transportation open source materials for the GAN algorithm to create vibrant colors, a heavy cyberspace-time response to the hesvy past. The artist also wants to express in this series: the history that is happening now is in history per se. Time is not purely linear. All that we have in the present is the result of the future.
