On sunny days, when the sun shines and a certain amount of wind blows, light is led into the space from the pipes in the ceiling, creating a phenomenon of light that looks like drops falling onto the surface of water. The light constantly moves with the wind and falls to reveal new sights. This architectural space is a remarkable manifestation of the seasonal, daily and time-of-day changes caused by the atmosphere, and the sights that can be experienced differ depending on the time of day when you visit. It is an accidental creation of nature, that humans cannot manipulate. All the phenomena produced by this work are forces of nature. Without the sun's rays, the phenomena themselves would not be created. Also, if the wind doesn't blow, it doesn't create an important movement. His idea of sustainability for the natural environment is to visualise the beauty of nature as it exists in the present moment, right in front of us. The natural environment that exists around us - the sky, the sun, the wind, the temperature - are all indispensable. He believes that to ensure that this nature is not destroyed and is connected to the future, we must first recognise its beauty as it exists in our immediate surroundings.
