LUX OSCILLANS – Colombia

It is an audiovisual suite in four movements where sound, analyzed in real time, governs the light emission of an anisotropic field: grain, halo, matter and radiance are organized and dialogue, composing generative systems of a poetic physics.

Audio generated using SuperCollider, free software.

Moving image generated using C++ and JavaScript. 

BIO

Poet, interdisciplinary artist, composer, and psychologist. Alfonso questions the interface and the cyborg’s stance in its contemporary condition, transforming techno-spiritual and techno-emotional contexts in interaction with the machine. He conceives of sound as an entity, a material to be sculpted like stone. 

MOSS
Depuis le début de la pandémie, la pollution de l’air a diminué dans de nombreuses régions du monde. Nous assistons à un moment sans précédent en termes de réduction des émissions industrielles et de l’empreinte carbone. Moss est une sculpture sonore cinétique alimentée par des données sur la qualité de l’air générées par l’indice mondial de la qualité de l’air. La sculpture vivante est conçue pour analyser l’air de nos villes et réinterpréter les données avec des modes de respiration et des paysages sonores en évolution. De Berlin à Bombay, Moscou et Pékin. Le public peut expérimenter en temps réel la qualité de l’air du monde transformée en une installation sonore cinétique. Le projet contribue à la recherche mondiale et incite les citoyens à participer au débat sur la qualité de l’air et la démocratie sur terre. Moss vise à créer un engagement civil en apprenant de la sagesse de la nature et du service de la technologie.

Terraforming
The video work “terraforming” focusses on the transformation of a natural environment through energy input. The underpinning idea is that of three phase system change. This begins with the stage of equilibrium where a system is in a certain balance and not changing at all. In the next stage an evolving system enters a state of motion and change where it moves away from equilibrium. The third and final stage is the phase of transformation in which the original system becomes something else. The key element in this transformation process is the sun. This process is called terraforming, whereby a hostile environment, i.e. a planet that is too cold, too hot, or has an unbreathable atmosphere, can be altered to make it suitable for human life. Such a process is not merely a futuristic scenario but represents exactly what is happening on Earth at this moment as the process of atmospheric change brought about by increasing CO2 emissions heats up our planet and speeds up the process of climate change.

Moving atmospheres
Moving Atmospheres, the tenth Garage Atrium Commission curated by Iaroslav Volovod, is a partially mirrored sphere suspended in the air, propelling us towards an Aerocene epoch. We call towards this new era with Aerocene. For more than a decade we have been imagining a world free from the carbon, extractivism, capitalism and patriarchy that fuels some forms of life, a new way of being with the atmosphere and emissions-free travel, free from solar panels, lithium, helium, hydrogen and fossil fuels. This new era stands in stark contrast to the lingering eco-traumas of the Anthropocene, the current geological age in which some human capitalistic activity has been the dominant influence on climate and the environment.

Atmospheric Forest
Atmospheric Forest is a large scale VR point-cloud installation that visualizes and sonifies the relations between the forest and climate. It reveals the interaction patterns between the pine-tree emissions in Pfynwald, an ancient Swiss Alpine forest, and weather conditions in this valley, effected by drought. The trees do not only produce oxygen, but they are living bodies who breath too. I.e., they emit part of carbon dioxide, sometimes even up to 20 perc. from what they have consumed. When trees die, they release all the carbon they have collected during their lives back into the atmosphere. Atmospheric Forest explores the effects of drought on local forest ecosystems, and how such stress situations influence production of resin and volatile emissions (such as usual pine-tree scent).

Water and Bonsai

In his continued forays into experimental botany that blur the lines between art and science, artist Makoto Azuma (previously) has reimagined the bonsai tree, one of the oldest Japanese artforms. This latest work titled Water and Bonsai, began with a dead branch from a juniper tree which was carefully attached to java moss meant to simulate the form of leaves. The entire piece was then submerged into a modified hydroponic environment similar to some of his earlier aquatic plantscapes replete with LEDs, a filtration system, and C02 emissions that encourage photosynthesis.

Green Cloud (Nuage Vert)
The third edition of Nuage Vert (Green cloud) highlighted the cloud of vapour emitted by the largest waste incinerator in France, on the edge of Paris at Ivry-sur-Seine, using a green laser beam which draws the clouds outline in real-time. Beyond the spectacle of the projection onto a power plant emission, Nuage Vert is also an open space, a canvas onto which each individual can project their questions concerning our consumer-waste culture, adding a second level reading to a site which is both highly visible and ignored.
The work acts like a semantic parasite, an organism that takes cover and feeds itself by establishing a sustainable interaction with another organism, in a relationship that is not necessarily damaging for the host, but necessary since the emission cloud provides Nuage vert with its visibility. During two years the project generated a social-cultural process which attracted support from citizens and the power plant owner, but however led to political obstruction from the local authorities. Escaping from a political stalemate, the work was realised without institutional consent, from a secret location on a private rooftop with the cooperation of local residents.
The project was previously realised in Helsinki, Finland and in Saint-Ouen, France.

Flightpath

“Flightpath Toronto’s swarms of flying people experiment with an urban-scale participatory proposition: one that demonstrates the pleasures of emissionless urban mobility and creates a shared memory of a possible future. Flightpath Toronto is a collaboration between Usman Haque, architect/artist and Natalie Jeremijenko, engineer/artist, uniting his expertise in participatory urban spectacle with her expertise in bird flight and urban natural systems.”A panoramic 4-loop animation showed imaginative 3D-generated city featured some art projects by Usman Haque and Natalie Jeremijenko from a “flyer” ‘s point of view. Images of the art projects gradually appeared in each loop.

Domestic catastrophe Nº3: La Planete Laboratoire
in collaboration with Dr. Jean-Marc Chomaz, Ladhyx, École Polytechnique

An aquarium containing a domestic globe, a motor to turn the globe and electronic valve or drip feed which releases a fluoresceine tracing dye onto the sphere. As the sphere turns, the green dye wraps itself around the sphere, enveloping it in what appears to be a thin gas or atmosphere that surrounds the planet Earth. The difference between emissions and atmosphere, the ‘man-influenced’ and the ‘natural’ climate cannot be easily defined.

Camera Lucida: Sonochemical Observatory
Camera Lucida (chamber of light or lucidity) directly transforms sound waves into light emissions by means of a phenomenon known as sonoluminescence. After adapting to the darkness surrounding the installation, one gradually perceives the detailed configurations of glowing sound fields.
