“The Sandcastle Rebuild Project” demonstrates the correlation between humanity and the digital world. Inspired by “Tower of Babel”, the interactive performance symbolises the re-establishment of human communication and cooperation through a unified computer language. Hence, it advances technological progress and the development of artificial intelligence. Throughout the process, humanity ceaselessly attempts to break down the boundaries between actuality and virtuality and showcases the mutual evolution of human beings and artificial intelligence through this interactive performance. The artwork combines visual arts and sound design to create a convergence of digital experiences in between virtual reality. It attempts to show the development of human civilisation and its coexistence with technology. Not only does it serve as a reflection on technological advancements, but also a discussion on ways of the future lifestyle. The experiential journey resembles the layer-by-layer construction of a tower within an immersive space, and it fosters a profound conversation intertwined with the destinies of humanity and technology.
