null² is a monument that centers on the philosophy of "Form is emptiness, emptiness is form" (空即是色・色即是空) and "Forging Lives," reinterpreting in a contemporary way the aesthetic sense of "polishing" that Japan has maintained since the Jomon and Yayoi periods. Historically, Japan has sought beauty and spiritual fulfillment through refined craftsmanship, seeing polished surfaces as symbolic manifestations of the sun, the cosmos, and harmonious order. Beyond nations and corporations, "artists creating a pavilion" itself is a social sculpture, forming a new landscape in the 21st century World Expo. The architecture itself is a massive sculptural work, integrating technologies such as specially designed mirror membranes, LEDs, and robots that have been uniquely engineered from their materials. null² embodies this traditional spirit while creating a new type of monumental landscape suited to the 21st-century Expo—an artistic statement of Digital Nature, a profound engagement with social sculpture, and a reflection of the artist's role in reshaping society.

Inside the massive space utilizing custom-made LEDs and mirrors, visitors engage in dialogue with digital humans. Through linguistic communication, visitors experience "letting go of symbolic representation." This questions the essence of human existence that remains after humans have ceded symbols to AI and computers, allowing for a rediscovery of self and society through language. Here, visitors engage linguistically with digital humans—autonomous digital twins called "Mirrored Bodies." The linguistic exhibition interrogates humanity's relationship with symbolic representation, particularly as it becomes increasingly displaced by AI. This exchange encourages participants to consider their identities as post-symbolic beings—primitive sapiens who have relinquished their dominance in intellectual and symbolic realms.

Complementing the linguistic exhibition is an immersive, non-verbal installation mode. In an infinitely reflecting light space, non-verbal installations reminiscent of artificial life and the Game of Life are presented. In this state where representation is stripped away, it becomes a space where one can sensorially and intuitively experience the essential structure of life. Through the infinitely expanding digital water surface, the boundaries between self and environment become ambiguous, presenting a new sense of life.

The exterior is composed of a special elastic mirror membrane designed specifically for null² that reflects and transforms the surrounding landscape in real-time, converting the scenery itself into a living sculpture. As a new type of mirror for the 21st century, it becomes a symbolic presence in the ever-changing urban landscape. This innovative mirror architecture exemplifies a contemporary reinterpretation of traditional Japanese reflective aesthetics, setting a new benchmark for 21st-century landscape design.

The tea room of null² incorporates the concepts of traditional Japanese tea spirit and mandala-like space. The entire architecture is connected to the tea-like spirituality and Japanese aesthetics, redefining them in the context of digital nature civilization. In reference to Osaka, a golden robotic arm inspired by the Golden Tea Room moves the membrane, creating a symbolic exhibition where tradition and technology intersect.

The null² Pavilion Shop Exhibition presents a historical and logarithmic timeline (log order) of humans and technology, demonstrating how humanity has continuously engaged with expression and symbols through iconic representations such as butterflies (Zhuangzi's Butterfly Dream), mirrors, swords, haniwa figurines, ukiyo-e prints, noh theater, and reproduction arts. The exhibition questions how contemporary art is positioned within these historical contexts, encouraging viewers to engage in deep historical and philosophical reflection. It presents iconic cultural artifacts such as Zhuangzi's Butterfly Dream, traditional mirrors, swords, noh masks, ukiyo-e, as well as modern technologies like telegraphy and duplication arts.
