There is a strong attraction to the fragile beauty of nature, which is always changing and never the same scene twice. It can only be seen when the conditions are right - sun, clouds, wind. A rainbow, for example. When it rains and the sun shines, we look at the sky to see if we can see a rainbow. The space of "Ripple" is just like that. When the sunshine arrives and the wind blows, it creates ripples of light in the space. The phenomenon of light falling from the pipes, appearing and disappearing on the ground, is reminiscent of a natural scene, like drops falling and spreading on the water. My aim was to create a new spectacle in an architectural space with an airy feel. In this space, time flows slowly and quietly.
