It is a design of a process, a function that generates new functions, rather than a design of a completed form. The light hardened resin solidified with light emitted by programmed LED, with the LED itself continuously changing its glow. The resin growing like ice pillars or a limestone cave shows various expressions by the lighting, and grows into a new shape from the emitted light. It is not an imitation of nature, but a process of artificial and natural integration that incorporates the principle of nature into artificial operation. The existence connects contrasting matters such as natural and artificial, autonomy and control, incomplete and complete. The installation creates a new environment that is neither natural nor artificial.
