Two stretched canvas sails change direction according to the wind, moving up and down as if nodding to each other. The airflow and wind resistance of the streamlined shape has been carefully calculated to allow it to capture every possible wind. In even the gentlest of breezes, it will continue to move, slowly and gently, never pausing. This work only comes to life when it merges with the wind, presenting an expression of great vitality. Susumu Shingu said, "It is necessary for humans to develop a sharp, rich sensitivity capable of feeling the rhythms of nature honestly, like plants fluttering in the wind, nurturing a supple strength and capable of adapting to any change." After graduating from Tokyo National University of Fine Arts and Music, he went to Italy, where he studied painting at the Academy of Fine Arts of Rome. He showed his first three-dimensional work in Milan in 1966 and has concentrated ever since on using the flow of wind or water, translating the invisible rhythms of nature into kinetic artworks that never fail to speak to us.
