Artificial Nature is a research project by Haru Ji and Graham Wakefield, creating a family of interactive art installations surrounding humans with biologically-inspired complex systems experienced in immersive mixed reality. The invitation is to become part of an ecosystem rich in living feedback networks, but not as its central subject. Although artificial natures are computational, we draw our inspiration from the sense of open-ended continuation and the aesthetic integration of playful wonder with the tension of the unfamiliar recalled from childhood explorations in nature. By giving life to mixed reality we’re anticipating futures inevitably saturated in interconnected computational media. However we believe computation is not intrinsically utilitarian, nor in opposition to nature; we see it instead as a material means to plunge even more deeply into what nature is, and find our place within it.

Since 2007, Artificial Nature installations have counted forty exhibits across nine countries, including festivals such as SIGGRAPH (Yokohama, Hong Kong), Microwave (Hong Kong), and Digital Art Festival (Taipei), conferences such as ISEA (Singapore) and EvoWorkshops (Tubingen), venues including La Gaite Lyrique (Paris), ZKM (Karlsruhe), CAFA (Beijing), MOXI and the AlloSphere (Santa Barbara), and City Hall (Seoul), as well as recognition such as selection in the international 2015 VIDA Art & Artificial Life competition and the 2017 Kaleidoscope Virtual Reality showcase.


AI / A-Life Data Art Installation: Projections, Sound, Evolutionary Neural Networks, Geospatial Visualization

Can data form a habitat for life? Infranet is a generative artwork realized through a population of artificial lifeforms with evolutionary neural networks, thriving upon open geospatial data of the infrastructure of the city as their sustenance and canvas. Born curious, these agents form spatial networks through which associations spread in complex contagions.

In this city as organism, the data grounds an unbounded, decentralized, open-ended, and unsupervised system. Non-human beings flourish in this environment by learning, discovering, communicating, self-governing, and evolving. The invitation is to witness, through immersive visualization and sonficiation of this complex adaptive system, how a new morphologic landscape emerges as a possible but speculative city.

Sand + sculpture with projected augmented reality, motion sensing, head-mounted virtual reality, large-scale projection.

As with its parents Archipelago and Inhabitat, Insuperposition is an ecosystem of vegetal and motile creatures subsisting on island-like topologies -- in this case five laser-cut topographies created by a combination of hand and algorithm, covered with a non-drying sand to allow reshaping. Visitor's shadows destroy and refertilize the land, and movements distribute thousands of seeds through the spaces between islands. With the VR headset visitors are shrunk to about an inch upon the islands, surrounded by foraging lifeforms, chirping their songs around the worlds. The change of spatial scale is echoed in a change of temporal scale on the large gallery wall, where a slow timelapse-scan around the islands gradually unfolds.

Conservation of Shadows

330kg salt, 12 nD::Node Arduino boards, 140 vibration motor-driven bells, 150m wire, Kinect sensors, projector, HTC Vive HMD.

A site specific work for a gallery in the Seoul Innovation Center that was previously occupied by the Korea Center for Disease Control and Prevention for medicinal storage and animal experimentation. For this historically charged space we imagined unknown new beings growing fond of the wet texture of old wood, the fragrance of sunshine smeared between cracks, and the quietness of murmuring and whispering. To let them live, we extended senses to mix realities surrounded by softly ringing bells and the crunch of salt underfoot as their shadows pass by; and an alternate perspective through head-mounted display in which we become the shadows around which new beings play.

Sand-sculpture augmented reality, head-mounted virtual reality, large-scale projection.

Inhabitat is a mixed-reality artwork of creative exploration within an alternate ecosystem of life-forms and a playful engagement with the complex interconnectivity of nature. It was exhibited at MOXI, The Wolf Museum of Exploration + Innovation, Santa Barbara, U.S.A., from August 2017 through January 2018, receiving around 65,000 visitors. Inhabitat was born out of a desire to bring biologically inspired complex systems into human-scale physical spaces while displacing the human from the center of the world. Inhabitat is a single world that awaits active observation and playful engagement through three distinct perspectives of scale and agency—three ways to see with other eyes. At the macro-scale, the entire world is experienced as projection-mapped landscape of sand upon a hand-sculpted substrate that forms the centerpiece of the exhibit. Visitors may wander freely around the landscape observing the behaviors of the alien life-forms that inhabit it as they busily forage, metabolize, reproduce and emit sounds. A mediated meso-scale view of the world is projected onto the museum wall behind. By donning a virtual reality (VR) head-mounted display, visitors enter the world at the micro-scale.

Endless Current

Virtual reality (head mounted display or surround projection and sound), artificial ecosystem.

Endless Current is a visualization of a complex biologically-inspired system. Through immersive display it presents an infinitely explorable world sustaining a virtual ecosystem of multiple species. These artificial life forms subsist within a simulated 3D fluid environment that is constrained by an amorphous landscape reminiscent of underwater or microscopic spaces. Immersed participants view virtual doubles of their hands and arms within this world, with which they can intuitively navigate the space and discover interactions with the simulated life.

Pair of Raspberry Pi, 10" screen, Korean traditional paper, 4" speakers.

An audiovisual animation and real-time generative simulation exploring boundary realms between the living and the non-living, familiar and alien, body and world. A human form is inhabited by a writhing algorithmic network in which each segment tries to maintain its relationship with another, bubbling and crackling as it evolves. It is a self portrait, both in terms of its metaphorical play of nature and artifice, as well as by synthesizing earlier independent work by each of the artists with a scanned point cloud of the artist’s body.

Chronophotography / Chronosculpture

Lenticular print, 3D print

Exhibited at: Media + Life: Sensorial Collaboration. College of Art, Tokyo Polytechnic University, Tokyo, Japan. 2013-02-04 - 2013-02-07 (Curated).

This work reprises Étienne-Jules Marey's technique of chronophotography with its original biological motivation, and yet is entirely artificial. The subject is an artificial life form composed of segmented sections comparable to the class Chilopoda (centipedes), but with trifold symmetric limbs that undulate to propel the organism through a fluid medium. The resulting forms are a product of the organism morphology, the propulsive patterns of its limbs, its predatory macro-behavior, and the viscosity and currents of the fluid it is immersed in.

Time of Doubles / Flux

Curved screen, mixed reality, artificial ecosystem.

Time of Doubles is an immersive interactive art installation. It invites visitors to experience mirror existences of themselves taking upon new roles as sources of energy and kinetic disturbance within a perpetually changing virtual ecosystem, a uniquely created computational world. Visitors encounter their doubles in an immersive world through 3D depth cameras, a surround array of active loudspeakers, and projected images. This world displays some characteristics familiar from our own, but is populated by unfamiliar life forms singing, swimming, and breeding through sensitive motions of dark fluids. The visitors’ doubles are energy fields, which emanate myriad bright fluid particles, food sources to be eaten by the virtual organisms. Visitors see, hear, and feel how they are fed to unknown species in this virtual ecosystem. Without visitors, the world-fluid is filled with life seeds that cannot grow, but with human presence the populations explode into alien orchestras of evolutionary growth. Larger organisms hunt smaller ones, leaving physical residues and films behind as they pass, which constrain the fluid flows, and which can be sculpted by visitors’ doubles as they approach them.

City Life

LED media facade 78 x 99 meters, animation.

  • Urban Organism: Triangle Screenscape. Seoul Square media facade. Seoul, Korea. 2011-10-11 - 2011-10-30 (Juried).

City Life (도시 생명) is a site-specific generative video for the Seoul Square venue - a media facade of 99x78m located in the heart of Seoul's cityscape. To express a 'world-as-it-could-be' in which city and artificial life coexist, it presents an biological analogue of a metropolis in which the subjects are not citizens, but the city buildings themselves.

The significant challenges of this venue include the vast size of the display, the very low resolution of pixels, and the fact that the office windows are often lit. The animation thus includes a population of virtual buildings, allowing a trompe l’oeil effect whereby the actual windows appear to be part of these virtual buildings, emphasized by the high contrast. The buildings represent a human element at a vast scale, but also animate in the form of growing and undulating life forms. Other alien organisms invade the space and consume these buildings, somewhat akin to Kaiju. A toon-shading rendering style is used to minimize the challenges of working at a low pixel resolution.

Genetic Morphologies

Generative/evolutionary 3D animation, print

Exhibited at: Cross-Reality: Traversed & Encompassed Vision. Arts & Information Center, College of Art, Tokyo Polytechnic University, Japan. Feb 20-22 2012.

Genetic Morphology Study is an initial exploration into evolutionary algorithms; a guiding aesthetic prototype for evolving populations of organisms as visual and spatial expression. The intention is to create a biological boundary form between the mathematical and the organic: modular combinations of geometric primitives developed through genetic evolution within a sculptural animation of collective behaviors. Each organismʼs morphology consists of a number of helix and hypercube modules arranged with symmetries varying according to their individual genetic code. The collective behavior of the organism is influenced by its nearest neighbor and the attractions of two ʻstarsʼ. The simulation comprised five generations of fifty agents each, produced by modeling in Maya and programming in MEL (Maya Embedded Language).

Haru Ji

Haru Ji is a TransArtist and researcher exploring the subject of life in art through Artificial Life Worldmaking: a form of computational generative art creating and evolving virtual ecosystems as immersive environments. She holds a Ph.D. in Media Arts and Technology at the University of California Santa Barbara and is an assistant professor of Art & Technology in the School of Consilience at Sogang University in Seoul, Korea. She attained a Master and a Bachelor of Fine Arts in Sculpture from Seoul National University, and studied image engineering, computer graphics and 3D animation at Chung-Ang University, both in Seoul, Korea. She has exhibited computational installations, digital sculptures, virtual architecture, video installations, sculptural objects and 3D animations at exhibitions and art festivals worldwide including ISEA, EvoWorkshops, and SIGGRAPH, with corresponding publications. She is a co-creator of the research project and immersive ecosystem "Artificial Nature", exploring the expansion of media art towards ‘art-as-it-could-be’. It is an amalgam of play, research, and art, which raises novel and significant questions regarding the trans-disciplinary interpretation of both subjective beauty and objective truth in art and biology.

Graham Wakefield

Graham Wakefield's research has evolved from computer music composition to the generation of open-ended environments for exploratory experience, emphasizing continuation over closure. This work is expressed through software design for creative coding, and immersive artworks of artificial ecosystems (both leveraging live system evolution through dynamic compilation). He is Assistant Professor in the School of Arts, Media, Performance and Design at York University, Toronto, where he runs the Alice Lab for Computational Worldmaking. He holds a BA in Philosophy from the University of Warwick UK, a Master in Composition from Goldsmiths College University of London, UK and a Ph.D in Media Arts and Technology from the University of California Santa Barbara, USA. Graham played a central role in the development of software systems and authoring content for the AlloSphere: a three storey spherical multi-user immersive instrument in the California Nano-Systems Institute. Graham is also a software developer for Cycling '74, co-authoring the Gen extension for the widely-used media arts environment Max/MSP/Jitter. His works and publications have been performed, exhibited and presented at international events including SIGGRAPH, ICMC, NIME, EvoWorkshops and ISEA.
