Beneath is an outdoor interactive installation inspired by the underwater world. The visual interaction creates experiences of being in the underwater world. It allows audiences to explore undiscovered territories and experience the unique visual expression of natural elements. The invisible natural world becomes visible and accessible in an “unusual” real-space. Beneath consists of a series of 5 visual elements: ‘Water Ray’, ‘Turbulence’, ‘Dropping Star’, ‘Water Cloud’ and ‘Flying Jellyfish’. The visual elements express the energy, living conditions and living organisms of the underwater world. It embraces communication in a silent world through gestures of interaction and abstraction using computer technology and motion tracking.
