In City Matrix, the artist uses symbols of metropolitan cities or technology (such as neon lights, LED, or advertisement board) to satirize that the artificial digital world which human beings indulge in has continuously been constructed and decorated by the digital technology. Although the splendid light and dazzling sounds are as attractive as butterflies, they in fact allure humans to be away from nature into a fantasized illusion without knowing it. Therefore, the artist uses the “alien-like” shapes of creatures to symbolize that the metropolitan cities we live in are like a strange matrix which is reproducing more and more aliens. Viewers are allowed to peek into the magnificent light and shadow of the advertisement boards within the matrix through concave and convex lenses. The silhouette of the flying butterflies reminds us the kaleidoscope-like city which is accompanied by the traffic noise. The antennae extend beyond the matrix, while at the end of the antennae are the digital butterflies reproduced by the matrix. Meanwhile, the color light from the LED creates the fantasized movement of the artificial light, capturing our attention through a clone with its stunning beauty.
