QUBIT AI

In its 25 years of existence, the International Electronic Language Festival (FILE) is an internationally renowned Brazilian project that since 2000 has explored the intersection between art and technology. With more than two decades of history, the festival stands out for fostering exhibition spaces and debate about artistic innovations driven by disruptive and innovative technologies, inviting the public to get involved with experimental forms of art that challenge the boundaries of conventionality. Currently, two of these technologies stand out in the contemporary scenario: the accelerated development of quantum computing and artificial intelligence corroborated by synthetic data.

Quantum computing, an emerging revolution in the technological field, offers a new range of creative possibilities for contemporary artists. This new era allows the exploration of unprecedented frontiers through a new computational format that consists mainly of quantum superposition and entanglement, a new field of exploration for synthetic computer science, as well as for the arts in general; on the other hand, artificial intelligence, fueled by synthetic data, offers artists a new way of making and understanding art, opening up space for new forms, concepts and artistic expressions.

Entitled QUBIT AI, the exhibition delves into this unexplored territory presenting a selection of works of art resulting from the connection between artistic creation and technology, proposing a theoretical reflection on what the interrelationship between quantum computers and synthetic artificial intelligence will be.

Visitors will be invited to experience immersive installations, experimental videos, digital sculptures and other forms of interactive art, which intertwine reality and imagination. The exhibition encourages reflections on the influence of technology on art and contemporary society, while at the same time providing an environment to compare already established technological arts (analog and digital) with the possible futures of art in the synthetic era, enhanced by quantum computing. The QUBIT AI exhibition at FILE SP 2024 transcends the mere presentation of works of art; it is a journey to the limits of human creativity, driven by the convergence of art, science and technology.

Marc Vilanova – Cascade – Spain

Waterfalls are a continuous source of infrasonic frequency found in nature. Although inaudible to humans, they play a crucial role in ecosystems, especially for migratory birds who use them as a compass. However, many waterfalls have lost their frequencies due to climate change. The work creates an immersive experience in which the audience interacts with the visualization of sound waves, experiencing the vibration of sound through illuminated strings.

Bio

Marc Vilanova is a sound and visual artist who works at the intersection of art, science and nature. Vilanova’s artistic production has always been led by a spirit of innovation fueled by an interest in new media. His practice combines sound/light installations, performance, and sculpture.

The Sea

FILE 2024 | Installations
International Electronic Language Festival

The Sea is an extraction of a complex natural phenomenon, resulting in an artificial emulation that develops a life form of its own. Just like the sea with its endless waves, this artificial system follows the impact of an immersive state, leading to a unique vision of an artificial generator. Despite appearing chaotic, it is capable of generating associations ranging from the movement of waves to science fiction scenarios.

Bio

Paul Gründorfer develops process-related systems and explores variable or unstable conditions in the occurrence of sound when exposed to amplification, feedback, and multiple signal streams. His works focus on processes that evolve in a social space. Leo Peschta is an artist and researcher.

SurrealismToday.com – The Legend of Ogie – United States

What worlds exist beyond Einstein’s speed limit? Inspired by Eric Weinstein’s theory of Geometric Unity, the work explores the idea that space-time is like a melody playing over an eight-dimensional universe. Abstract and metamorphic forms transition from organic forms to parastatic patterns, creating a dance of visuals and sounds that merge into an immersive experience of fractal unfolding.

Bio

SurrealismToday.com is an artist collective and educational platform dedicated to the proliferation of surreal and visionary ontologies in contemporary art. The group began as an esoteric cargo cult dedicated to discovering the beautiful, the fantastic, and the transcendent in the pseudo-philosophical landscape of the art world. His methods include searching for gems in the digital world and infusing mystical enchantments into generative diffusion models.

Bruce Nauman

Nature Morte
Nature Morte focuses on Nauman’s long relationship to his own studio, a variation on his four unique multi-projection videos, Mapping the Studio (2001). Three viewing stations, each consisting of an iPad linked to a wall-sized projection, provide an interactive exploration of the 3D studio space. Only now the artist is absent, and the participant becomes performer as he/she manipulates the large scale video projections on an iPad using touch control. The participant is free to navigate anywhere throughout the space, selecting broad vistas or individual objects. Using a hand-held 3D scanner, Nauman recorded hundreds of images that allow participants to select an object and locate close-up anything found there, and further reorient the image to see an object from above and below, and at times inside-out. The resulting mobility intensifies the experience of the viewer/performer. Presenting a static, but immersive re-creation of his studio space, Nauman’s pieces once again play at the tenuous lines between the body and space, perception and physical material.

BILL VIOLA

The Raft
The Raft depicts at life-sized scale a group of ordinary people casually standing together. Suddenly, they are struck by strong blasts of water that rush in, overtake them, and then, just as unexpectedly, recede. In the aftermath of the deluge, the victims huddle together, seek protection, and help those who have fallen. The viewer experiences this event in an immersive setting, standing in a darkened room and surrounded by the roaring sounds of the water. Meticulously captured in slow-motion, The Raft arouses a visceral experience of human calamity and shared humanity, provoking a consideration of the range of responses to crisis.

FACTORY FIFTEEN

Kokon
“Kokon ist eine sphärische, immersive Videoinstallation von 360 ° x 220 °, die wir im eigenen Haus entworfen, inszeniert und produziert haben. Cocoon platziert die Teilnehmer in mehreren Schalen abstrakter und figurativer architektonischer Räume, die sich langsam ablösen. Cocoon glaubt, dass Architektur nicht statisch ist, sondern vergänglich, sich entwickelnd und animiert. Unsere Stadt ist unser Kokon. “ Fabrik fünfzehn

Refik Anadol

Quantum memories
Quantum Memories is Refik Anadol Studio’s epic scale investigation of the intersection between Google AI Quantum Supremacy experiments, machine learning, and aesthetics of probability. Technological and digital advancements of the past century could as well be defined by the humanity’s eagerness to make machines go to places that humans could not go, including the spaces inside our minds and the non-spaces of our un- or sub-conscious acts. Quantum Memories utilizes the most cutting-edge, Google AI’s publicly available quantum computation research data and algorithms to explore the possibility of a parallel world by processing approximately 200 million nature and landscape images through artificial intelligence. These algorithms allow us to speculate alternative modalities inside the most sophisticated computer available, and create new quantum noise-generated datasets as building blocks of these modalities. The 3D visual piece is accompanied by an audio experience that is also based on quantum noise–generated data, offering an immersive experience that further challenges the notion of mutual exclusivity. The project is both inspired by and a speculation of the Many-Worlds Interpretation in quantum physics – a theory that holds that there are many parallel worlds that exist at the same space and time as our own.

Liz West

Our Colour
Does colour change the way you feel? What does it feel like to be inside a rainbow? For the 2016 edition of the Bristol Biennial British artist Liz West invited visitors to drench themselves in the spectrum. West transformed architectural space and turned colour into an immersive and embodied experience by refracting light through carefully arranged coloured theatre gels. A vivid world was created, exploring human visual perception and how colour affects our emotions and our bodies.

Refik Anadol

WDCH Dreams
The Los Angeles Philharmonic collaborated with media artist Refik Anadol to celebrate our history and explore our future. Using machine learning algorithms, Anadol and his team has developed a unique machine intelligence approach to the LA Phil digital archives – 45 terabytes of data. The results are stunning visualizations for WDCH Dreams, a project that was both a week-long public art installation projected onto the building’s exterior skin (Sept 28 – Oct 6, 2018) and a season-long immersive exhibition inside the building, in the Ira Gershwin Gallery.

HITO STEYERL

Factory of the sun
In this immersive work, which debuted at the 2015 German Pavilion at the Venice Biennale, Steyerl probes the pleasures and perils of image circulation in a moment defined by the unprecedented global flow of data. Ricocheting between genres—news reportage, documentary film, video games, and internet dance videos—Factory of the Sun uses the motifs of light and acceleration to explore what possibilities are still available for collective resistance when surveillance has become a mundane part of an increasingly virtual world. Factory of the Sun tells the surreal story of workers whose forced moves in a motion capture studio are turned into artificial sunshine.

Cocoon
“Cocoon is a 360° x 220° spherical, immersive video installation we designed, directed and produced in house. Cocoon places the participants inside several shells of abstract and figurative architectural spaces, which slowly peel away. Cocoon believes architecture is not static, but is transitory, evolving and animated. Our city is our cocoon.” Factory Fifteen

Initially started as a tweak of 115C8 in 2013, one of Kwok’s Algorithmic Creatures based on finite subdivision, 1194D is an experiment on multiple geometric creatures co-existing within a tetrahedron-based grid environment. In 2017, The project was improved and revised into an immersive triple-screen audiovisual installation as 1194D^3 for .zip Future Rhapsody art exhibition curated by Wu Juehui & Yan Yan at Today Art Museum in Beijing, China. The entire visual is programmed and generated using Processing. All stages are later composed and exported using Premiere.

Pedro Veneroso

file festival 2019
‘Tempo: cor’(Time:color) consists of an immersive installation that seeks to modify our experience of time by converting hours into color. A set of chromatic clocks, each set to a different GMT time zone, projects, in a semicircle, the current time in their mathematical and chromatic representations. The conversion between these two forms of time representation is based on an algorithm composed of sinusoidal functions that modulates the RGB colors as a function of the current time, gradually modifying the intensities of blue, green and red throughout the day: at midday yellow predominates, while at four in the afternoon the hour is red; midnight is blue, six o’clock in the morning is green. Side by side, the colors projected by the clocks merge, creating an immersive experience of a continuous and circular time, between the different time zones, that crosses the entire chromatic spectrum. This installation is part of a series of works in which I investigate the relationships between human notations and codes and our experience of space-time, seeking to change the ways we understand it; in this case, visitors immerse themselves in a spatial experience of time that provokes the questioning of notations and perceptions that we usually consider axiomatic. Changing the way we represent time will change our way of experiencing it?

Zee
File Festival 

Immersive Audiovisual Environment Artificial Fog, Stroboscopes, Pulse Lights and Surround Sound, 2008

ZEE proposes a state of tabula rasa and unfolds without a narrative or reproducible imagery.The audience wanders freely in a space filled with extremely dense fog that fully obscures all of its boundaries. Stroboscopic- and pulse lights illuminate the fog, in a softened and evenly dispersed manner, creating kaleidoscopic three-dimensional structures in constant animation. An ambient and minimal sound-scape connects to the imagery, without directly synchronizing to it.The core visual impression of ZEE is of a psychedelic architecture of pure light, an abstract luminescent landscape enveloping the visitor. Time appears to stand still.

Antonio Pio Saracino

INFINITUM
INFINITUM is an immersive art – architectural installation presented at the Sharjah Art Museum on the occasion of the Islamic Arts Festival 2019/20, 22nd Edition. Arches are typical in Mosques’ design. […] Islamic Arches buildings are typically constructed of stone, wood being rarer in the original Middle Eastern homelands of the Umayyads. The rows of Columns and Arches give a visual impression of limitless space, as a metaphor of the progress for human civilization, maximizing spiritual symbolism and visual appeal – progressing towards an ideal civilization. It refers to centuries of human civilization and the creation of prospective in social spaces and the openness to open possibilities of human life.

Light in Water Installation
‘Light in Water’ is a site-specific installation intended to provide an immersive and emotional experience. It was previously presented at Milan Design Week 2011. The installation took advantage of the unique status of the venue – one of the oldest concrete domes in Paris. The installation was thus adapted to the circular form of the space, defining the inner sanctuary as a ‘place to be’ and an outer area as a space for a bystander. There are sixteen rings of slotted tubes on the ceiling. From each hole, 60 drops of water fall every minute; in total 3 tons of water circulate in the space. The LED lights vibrate between on and off, with frequencies ranging from the shortest interval possible, at 7μs, allowing the viewer to materialise a point of light in water, up to 6000μs, where light becomes the line of water.

Jennifer Steinkamp

Jennifer Steinkamp uses computer animation to create video projections and immersive installations, dynamic works that explore the relationship between architectural space, motion, and perception. When projected, Steinkamp’s dimensionally modeled images create the illusion of receding space, generating a dialogue with the real space occupied by the viewer. Steinkamp’s imagery ranges from abstract undulating forms to subjects drawn from nature, such as the cascade of flowers in her 2008 series, “It’s a nice day for a white wedding.”

Sheela Gowda

Behold
Behold 2009 is an immersive large-scale installation by the South Indian artist Sheela Gowda. This work consists of four kilometres of hand knotted rope and approximately twenty car bumpers. The bumpers are suspended against the gallery wall, individually or in sets, from ropes made of braided human hair, which are knotted around the metal. The ropes extend irregularly between the hanging bumpers in small and large loops, as well as being gathered on the floor in piles and heaps, some of which can also be suspended from the ceiling. In this way the installation can take over a single gallery space or occupy a single stretch of wall.

ZEE

Expérience immersive forte alliant approche méditative et implication physique, Zee s’inscrit dans le travail sur la représentation humaine et ses ressorts psychologiques poursuivi par Kurt Hentschläger. Une expérience qui se suit comme un véritable fil d’Ariane.Savez-vous vraiment ce que signifie faire l’expérience physique d’une œuvre numérique immersive ? Ceux qui ont eu la chance d’expérimenter le Feed de Kurt Hentschläger, plongée radicale au cœur d’une matière instable de brouillard artificiel dense, de lumières stroboscopiques et de fréquences sonores électroniques pulsatives répondront sans doute par l’affirmative. Pour les autres, l’épreuve de rattrapage ultime aura pour nom Zee, pièce rare et prolongement de Feed, présentée au Centquatre parisien dans le cadre de l’exposition Trouble Makers, fil rouge de Némo, le festival arts numériques d’Arcadi Île-de-France. Ancienne moitié du duo de défricheurs numériques extrêmes Granular Synthesis, Kurt Hentschläger cultive le goût des environnements déstabilisants et trouve dans Zee le dispositif déambulatoire idoine pour nous prêter au jeu. « Zee fait partie de la même série de travaux que Feed, mais en format installation », explique l’artiste autrichien basé à Chicago. « Zee fonctionne en mode huis clos, dans un espace totalement fermé. Dès que l’on entre, le brouillard est déjà là. Il remplit l’espace dans lequel vous êtes invitez à vous déplacer. Par rapport à Feed, où le public reste assis à un endroit précis, il y a donc davantage de flexibilité dans l’expérimentation du dispositif. Cette idée de déambulation dans l’espace induit un climat différent. C’est peut-être encore plus intimidant pour certains mais pour moi cela donne à Zee une connotation plus méditative. »Procéder à l’expérience nécessite véritablement de se prendre en main.

フロリアン·ヘッカー
Sound Installation
In his installations, live performances and publications, Florian Hecker deals with specific compositional developments of post-war modernity, electroacoustic music as well as other, non-musical disciplines. He dramatizes space, time and self-perception in his sonic works by isolating specific auditory events in their singularity, thus stretching the boundaries of their materialization.
Their objectual autonomy is exposed while simultaneously evoking sensations, memories and associations in an immersive intensity. Some of his works incorporate psycho-acoustic phenomena, disorienting listeners’ spatial perceptions and expanding their conception about sound. Hecker’s most recent recording, Speculative Solution ( Editions Mego, 2011), brings together Hecker’s sonic practice and psychoacoustic experimentation with philosopher Quentin Meillassoux’s concept of ‘hyperchaos’ – the absolute contingency of the laws of nature.
During his residency at MIT, Florian Hecker will research a new sound piece that takes the concept of the “auditory chimera” as point of departure. Originally developed at MIT by Bertrand Delgutte, senior research scientist at the MIT Research Laboratory of Electronics, the concept of the auditory chimera inspires an exploration of the relationship between pitch perception and sound localization. Hecker will create a text and sound piece that incorporates the recordings of material read by students. Using an anechoic chamber he will work with students to explore the experiential nature of psycho-acoustic practice.
