Digital Nature, Existence from null to null: Encoded Eternity, Object-Oriented Primal Vow is an exhibition that relives Yoichi Ochiai's artistic and philosophical exploration of Digital Nature. Ochiai has been redefining the conceptual description of media art since early in his career (books: The Century of Magic, etc.), exploring the boundary between material ( tangible objects) and immaterial ( objects in the form of images and realities), and the landscape woven by Shingon Esoteric Buddhism and object-oriented world description. The entirety of Ochiai's work, inspired by Takayama's Homei-Tai, encompasses the Digial Nature, his unique Sehnsucht nach Masse and Dadaism, the genealogies of media art and video art in contemporary art history, and "phantom resonance," his interpretation of AI such as LLM and diffusion models that Ochiai's interpretation of AI, such as LLM and diffusion models. The installation, which will be presented at the site-specific Kusakabe Mingeikan, is based on the Mingei philosophy of Yanagi Muneyoshi, and pursues a unique beauty from the leap of contemporary computational progress. Ochiai's perspective explores the recursive generative process of Digital Nature, aiming for an automatic implementation of the mandala-like world description of Shingon Esoteric Buddhism, and an object-oriented salvation through the benevolence of Buddha (Object-Oriented Primal Vow). On this journey, materiality and digitality merge, and in the joy of life, Dadaism and dance music (or, as Ochiai calls it, "music of worms": a metaphor for the return to tactile musicality of data that transcends the visual and auditory senses) intersect with the East Asian mythological system that shows the mythological connection between Saru-Tora-Hebi (Monkey-Tiger-Snake) and Nue in Gifu Prefecture. A new phase of Digital Nature begins to unfold. The infinite development of matter and immateriality eventually reaches "null," an Ochiai-like computational Sanskrit word expression of "empty. This "null" is a compression of the void, color, and emptiness, and encompasses the possible world as a symbol of encoded eternity. Starting with this exhibition, Ochiai's new exploration of Discordは Nature, born out of his dense logical contemplation and artistic leaps, is a fusion of the humanities, computer science, ecology, and the arts. Object-oriented Bodhisattvas, Mingei, Digital Nature, and the new Shingon universe that shows sustainability will give irreversible changes to the viewer's consciousness objects.
