This project is divided into three parts: flowing colors, dancing jewellery, and a shop called Simulacra. I developed the theme of Simulacra for my exhibition, which explores the central theme of : dynamism in virtual space. Based on the exploration of materials and dynamics, I am fascinated by the combination of experiment and uncertainty, real and virtual, 3D form of digital jewelry and real, which can simulate the real and transcend the real existence. When attached to the digital material, the unexpected effect of watercolor ca provides surprises and happiness for creator and audience.
