Exhibited in the special exhibition “Alternative Computations — Worlds Otherwise Calculated” at the Quantum Art Festival (Jan 29 – Feb 1, 2026). The installation was experienced by more than 4,500 visitors over four days. The full movie is available via the link in my bio. — Alternative Computations, 2026 The universe computes. Life is computation. Mathematics is the language of this understanding. Change the language, the universe changes — the way of seeing changes. Sometimes, those in power choose which way of seeing prevails. What falls outside that choice is named error — and vanishes. Japan once possessed a distinctive mathematics — wasan. Calculation practised as beauty, play, and offering to shrines: festive knowledge comparable to haiku and the tea ceremony. In the late nineteenth century, the Meiji government introduced Western mathematics in pursuit of national strength. Wasan was expelled. The cosmos its culture alone could see was closed. At the destination Western mathematics has since reached stands quantum computing — yet its development is governed by utility and optimisation. Quantum noise is expelled as error. But quantum noise interferes, entangles, carries the past. There is another cosmos. This work recaptures it through the play and festivity of wasan. The Alternative Computations series sculpts the cosmologies of lost vernacular mathematics. Built from quantum noise discarded by mainstream computing, this automated instrument takes sky, earth, and human as its three-layer structure. Twenty-eight sangi orbit overhead as the Twenty-Eight Lunar Mansions. A tatami floor defines the sacred threshold. More than four thousand reeds fill the space. The dancer’s movements, the tea master’s gestures, audience presence, and meteorological data are thrown into a quantum computer embedded in the ceiling’s sangi mechanism. High-dimensional dynamics set the sangi’s orbits and descend as rain sound. Mechanical creaking holds the weight of matter, anchoring experience between dream and waking. Thunder, wind, insects, cranes and frogs — a 28-minute sound collage. Each cycle ends a universe; another begins.

Quantum Art Festival 2026 Special Exhibition “Alternative Computations: Worlds Otherwise Calculated” Gunpowder can become either a weapon or fireworks. This exhibition takes wasan—traditional Japanese mathematics, once a playful culture alongside haiku and the tea ceremony—as its point of departure, reclaiming calculation as a site of festivity rather than mere efficiency.

Fabricademy (@fabricademy ) Online courses in digital fabrication, biotechnology, and other skills necessary for the fashion production of the future. The multi-disciplinary field of fashion may be the hub concept for a comprehensive and creative education. - Reference and Image Credit: / #METACITY #city #design #art #instacity #fashion #technology #digitalfabrication #biodesign #textile #biotechnology

"School for Poetic Computation" (@sfpc_nyc ) “Poetic Computation" is a term that refers to the search for creative ways of using computer technology that depart from conventional economic principles. This is the philosophy of the School for Poetic Computation, an alternative school in New York. Poetry is an attempt to describe the indefinite world, and it may be the shortest path to learning the nature of computers. - Reference and Image Credit: https://sfpc.io/ #METACITY #city #design #art #instacity #technology #computation #programing #mediaart #poetic #coding

"Tokyo Art Junior High School" (@gaku.school ) An art school held at GAKU, a creative learning space located on the 9th floor of Shibuya Parco. Here, leading professional creators such as Makoto Aida, Keiichiro Shibuya, and Koharu Sugawara are invited to give lectures and workshops on multiple fields related to creativity. What is needed to stimulate the creativity of the next generation? One of the most important explorations of this question is to be found here. - Reference and Image Credit: https://gaku.school/class/geichu2022/ #METACITY #city #design #art #instacity #education #community #music #dance #mediaart #empowerment #children

"University of the Underground" (@uniundergrd ) "University of the Underground" is a free educational program held in the basement of a nightclub in Amsterdam. Organized by Nelly Ben Hayoun ( @nellybenhayounstudios ), with Paola Antonelli and Hans Ulrich Obrist on the board, the program aims to train people to challenge existing structures. The school is truly a melting pot of alternatives swirling underground. - Reference and Image Credit: / #METACITY #city #design #art #instacity #underground #amsterdam #alternative #speculativedesign #criticaldesign #criticism

"Self-Learning and Technology" Sugata Mitra, an educationalist, installed freely accessible computers throughout the slum. As a result, the children's academic performance increased dramatically within a few months. If technology is bringing a new equality to the world, what is the real need for education there? - Reference and Image Credit: /talks/sugata_mitra_the_child_driven_education https://abject.ca/the-hole-in-the-wall-the-holes-in-my-thinking-and-my-life/ #METACITY #city #design #art #instacity #education #community #technology #empowerment #children #selflerning

“Magick.Me” Magick.Me ( @magick.me ) is an online magical school for art and consciousness transformation classes Study a cross-section of ancient and modern techniques, including meditation, yoga, tarot, and chaos magic. Learning "magick" as a technology intricately interwoven with religion and culture may lead to the exploration of a new cross-disciplinary way of knowing. - Reference and Image Credit: https://www.magick.me/ #METACITY #city #design #art #instacity #anthropocene #education #community #magic #magick #meditation

“The Nomadic University (Idou Daigaku)” Minerva University ( @minervauniversity ) is famous for having no campus. Jiro Kawakita was several decades ahead of Minerva University in attempting to do the same thing. In his mobile university, 100 people live in tents and travel around Japan to conduct outdoor workshops. How can we regain the scale of a "square" that is neither too large nor too small? - Reference and Image Credit: /blog/satolog/8697/ http://ankei.jp/yuji/file/0909/000785_1.pdf https://honto.jp/netstore/pd-book_01431912.html #METACITY #city #design #art #instacity #anthropocene #education #mobility #community #environment #nomad

“Black Mountain College” Black Mountain College ( @bmcmuseum ) is the gold standard for progressive educational communities in the 20th century. John Cage and Buckminster Fuller were among its instructors. It functioned as a generative place where instructors and students complemented and enhanced each other through cross-disciplinary education and discussion. Where are the sources of culture in the 21st century? - Reference and Image Credit: / /wiki/Black_Mountain_College #METACITY #city #design #art #instacity #education #community #BlackMountainCollege #BuckminsterFuller #JohnCage #Bauhaus

April Theme: “CITY and LEARNING” METACITY collects and introduces examples from around the world that show a glimpse of "possible cities.” What does it mean to learn in a city today, when people everywhere are increasingly able to learn in all kinds of places? https://metacity.jp/ #METACITY #city #design #art #instacity #anthropocene #education #university #learning #school #community

"The Countryside as a Neo Utopia" The countryside is being reshaped by the proliferation of data centers of global corporations. The countryside is now being consumed as a device external to the city. Autonomous machines, plants and animals are moving in the countryside without humans. Such a new symbiotic zone where machines and nature are in harmony may be the new utopia of the countryside. - Reference and Image Credit: CAPTCHA /en/article/computational-landscapes-and-the-new-sublime /ja-jp/editorial/culture-ja/rural-futurism-2?lang=ja https://wired.jp/special/2019/machine-landscapes/ #METACITY #city #design #art #instacity #anthropocene #architecture #countryside #landscape #datacenter #sublime
