This glass changes color through the conduction of electricity. It creates a scene of “moonlight in front of the window.” When the power is off, this window is frosted.But once the power is turned on, the window becomes transparent, and the words on it appear.The scenery outside with the lines provides infinite space of imagination. While this artwork echos the “Moon” in the theme of “Mirror, Flower, Water and the Moon,” it also gives answer to the core concept of “revelation” and “concealment” through its change. In addition, the artist Qiu Zhijie wrote a sentence beside this work: “The most difficult thing for animals to understand is the glass,” and the fourth story of “The Mirror of the Philosopher King” is hidden here.
