Ozeki comments, "(The artwork is) based on the theme of “Gardens.”
In Japan, gardens are made not only with plants, but also with natural stones and sand. Sometimes, stones are used as decorations, as in bonsai.
Given that there is a form of psychotherapy called "box garden therapy,” I think gardens are like mirrors that reflect the human heart.
The artwork titled Sand Ripples depicts a karesansui (dry landscape garden) that expresses natural scenery without using any water. In such gardens, Sand Ripples—the patterns in the sand—are one of the elements used to represent the flow of oceans and rivers.
