Digital artwork of a large golden birdcage

Ai Weiwei, Gilded Cage AR, 2021

b.1975, China

Lives and works in multiple locations, including Beijing (China), Berlin (Germany), Cambridge (UK) and Lisbon (Portugal)

Gilded Cage is an iconic work by multidisciplinary artist and activist Ai Weiwei, originally created in 2017 as part of a global migration campaign titled Good Fences Make Good Neighbors (a line taken from the 1914 poem Mending Wall by acclaimed American poet Robert Frost). Meticulously translated into the medium of AR and augmented into the different botanical gardens, this large-scale gilded cage addresses power structures, habitats, borders, confinement, and restriction, but also care giving, preservation, and nurturing. The work invites viewers to enter and walk through it, experience the different cells and turnstiles, while viewing the gardens from within, through its gilded bars, as a captured bird or an imprisoned man would.

Ai Weiwei is a multimedia artist who also works in film, writing, and social media. Major solo exhibitions include Serralves Museum, Porto, Portugal ; Cordoaria Nacional, Lisbon; Imperial War Museum, London; K20/K21, Düsseldorf; OCA, São Paulo; CorpArtes, Santiago; Mucem, Marseille; Fundación PROA, Buenos Aires; Sakip Sabanci Museum, Istanbul; Public Art Fund, New York; The Israel Museum, Jerusalem; Palazzo Strozzi, Florence; 21er Haus, Vienna; Helsinki Art Museum; Royal Academy of Arts, London; Martin Gropius Bau, Berlin; Hirshhorn Museum and Sculpture Garden, Washington D.C.; Taipei Fine Arts Museum; and Tate Modern, London.

Augmented reality art in a garden - white frame with moving waves of colour

Refik Anadol, Machine Hallucinations: Nature Dreams AR, 2021

b. 1985, Turkey

Lives and works in Los Angeles, USA

Refik Anadol’s work is based on a series of synesthetic reality experiments centered on how human-machine collaborations can help us experience nature in a new way. The journey starts with a sophisticated Artificial Intelligence algorithm trained on 68,986,479 million raw images of nature. Utilizing the dataset as pigment and AI as his collaborator, Anadol re-creates shapes, patterns, and colors of nature, transforming them into a hypnotic cycle of deconstruction and reconstruction of natural imagery, morphed into an AI “stream of consciousness.” The work is thus based on images of nature, yet offers an alternate reality that can only be seen through a mechanical lens. As viewers gaze into the machine’s mind, they are left to wonder about a future world where nature no longer exists and technology becomes the only way of remembering.

Refik Anadol is a media artist, director, and pioneer in the aesthetics of data and machine intelligence. Preferring difference over singularity and movement over stasis, his work locates creativity at the intersection of humans and machines. Anadol’s site-specific AI data sculptures, live audio/visual performances, and immersive installations take many forms, encouraging viewers to rethink their engagement with the physical world, its temporal and spatial dimensions, and the creative potential of machines.

El Anatsui AG + BA (AR), 2014/2021

El Anatsui, AG + BA (AR), 2014/2021

b. 1944, Ghana

Lives and works in Nigeria

El Anatsui’s iconic bottle-cap installations are created from thousands of aluminum bottle-tops wired together with copper, thereby catalyzing the transformation of familiar, mundane objects into startlingly poetic works of art. The frugality of the materials stands in contrast to the shimmering and grandiose effect they accumulate through the artistic process and manner of installation as large-scale hanging sculptures.

For this exhibition, a two-part work has been translated to AR, inserting light movement into the flexible materials. Installed in the open space of the gardens, the work accumulates gentle movement, as if soft breezes blowing through the gardens play over its surfaces. Like many of Anatsui’s pieces, the work addresses both artistic and political issues, and resonates with notions that confound art and craft, high and low, center and periphery.

Anatsui’s works are held in major international collections, including The British Museum, London; Centre Pompidou, Paris; de Young Museum, San Francisco; The Metropolitan Museum of Art, New York; National Museum of African Art, Smithsonian Institution, Washington D.C.; Kunstpalast, Düsseldorf; Tate Modern, London; and many others. Large-scale external installations include: Ozone Layer and Yam Mound at the Alte Nationalgalerie, Berlin (2010); Broken Bridge I at Musée Galliera, Paris (2012); Broken Bridge II on the High Line, New York (2012/13); and TSIATSIA – Searching for Connection (2013), his largest bottle-cap work to date. This shimmering tapestry of light embellished the façade of the Royal Academy of Arts, London, during its 245th Summer Exhibition.

Ori Gersht, Forget Me Not, 2021

Ori Gersht, Forget Me Not, 2021

b. 1967, Israel

Lives and works in London, UK

Ori Gersht’s work toys with classic art historical conventions by evoking a 17th-century Dutch still life through hyper-realistic digital creation. The work presents a lush, sensuous bouquet of flowers set amidst the botanical gardens, accompanied by an accelerating bee hum that becomes almost unbearable. When the visitors are at touching distance, a violent explosion occurs, and the bouquet shutters into pieces that fill the air with fragments of glass, petals, stems, and insects, cascading slowly to the ground. The still-life image, created after Jan Brueghel the Elder’s painting Flowers in a Wooden Vessel (1606/7), is dynamically transformed into an animated Abstract Expressionist composition. Alluding to both the creation of the universe and the concept of vanitas (signifying the inevitability of death and the transience of all earthly things), Gersht’s work stands as a spectacular meditation on the infinite cycle of creation and destruction. Soon after the explosion, the voices of three scholars are heard, whispering in the grim void, as if carried by the wind; describing the once lush bouquet from a personal point of view, they offer different interpretations of the original painting that disappeared in the folds of time.

The work was developed from an earlier work by Gersht, Big Bang (2006), originally commissioned by the Victoria & Albert Museum for the 2006 exhibition Twilight, subsequently featured in Santa Monica, Boston, Washington, Germany, and the National Gallery, London. Gersht’s work has been recently featured in a number of exhibitions, including Unearthed: Photography’s Roots, Dulwich Picture Gallery, UK; Flowers in Art, ARKEN Museum for Modern Art, Denmark; and The Expanded Landscape, Getty Center, The J. Paul Getty Museum, California; among others. His solo show titled Becoming will open at the Yancey Richardson Gallery, New York in October 2021.

Augmented reality artwork, frames on stone-looking pedestals featuring an ice cave and a woman's face

Isaac Julien CBE RA, Stones Against Diamonds (Ice Cave) AR, 2015/2021

b. 1960, UK

Lives and works in London, UK

Isaac Julien’s Stones Against Diamonds (Ice Cave) draws inspiration from a letter written by Brazilian architect Lina Bo Bardi and was shot in Iceland’s remote ice caves in the Vatnajökull region. Over five days, the crew endured sub-zero temperatures in the heart of spectacular, glistening glacial caves formed in ice over thousands of years and only accessible a few days a year due to the harsh climate.

Thus, the artwork explores themes inspired by Bo Bardi’s letter, where she praises the beauty of semi-precious gems over preferred precious stones such as diamonds. Julien portrays some of the most beautiful objects as the least precious in a conventional sense. Signature elements of Bo Bardi’s work have been incorporated into Stones Against Diamonds (Ice Cave), including a staircase built by hand into the ice cave during the production of the film. Continuing the parallels, Julien integrates Bo Bardi’s trademark glass and concrete easels into his film.

Augmenting a five-screen version of Stones Against Diamonds (Ice Cave) into the different botanical gardens lends it additional layers by juxtaposing distant and near. In doing so, ecosystems’ characteristics are questioned: in their relative temperature – the cold and the warm digitally meeting – but also with regards to notions of natural and cultural, cultivated and wild.

Isaac Julien is a Turner prize-nominated artist and filmmaker; recipient of the Royal Academy of Arts Charles Wollaston Award; appointed a Commander of the Order of the British Empire (CBE) in 2017. He creates multi-screen film installations and photographs that incorporate different artistic disciplines to create a unique, poetic visual language. Recent exhibitions include a solo show at MAXXI, Rome, where Julien exhibited his series entitled A Marvellous Entanglement, and the very recent European premiere of his ten-screen installation Lessons of the Hour, at the National Galleries of Scotland (Modern One), heading the Edinburgh Art Festival.

Mohammed Kazem Directions (Zero), 2010/2021

Mohammed Kazem, Directions (Zero), 2010/2021

b. 1969, Dubai, UAE

Lives and works in Dubai, UAE

In Mohammed Kazem’s monumental work, viewers are invited to pass through a large-scale figure of the number zero on which numerous geographic coordinates, representing all countries of the world, are inscribed in numeric form. The work is based on the significance of the number zero – one of the first important innovations by a Muslim scientist. The course of history was changed when Persian scholar Muhammad Ibn Musa Al-Khwarizmi discovered the number zero and considered it a number within the field of algebra.

Originally conceived for the United Arab Emirates and the metropolitan city of Abu Dhabi, whose population is comprised of a diversity of nationalities, races, and religions, the work embodies the principle of coexistence and peace, inviting viewers to pass through it, as if starting anew from equal ground. As the day progresses, light, shadows, and reflections over the digital structure change, further enhancing the connection between the work and its natural surroundings.

Mohammed Kazem’s artistic practice spans video, photography, and performance, seeking new ways of apprehending his environment and experiences. The work is informed by his training as a musician. He was a member of the Emirates Fine Arts Society and is one of the Five, an informal group of Emirati artists at the vanguard of conceptual and interdisciplinary art practice.

Kazem has participated in numerous group shows, in Abu Dhabi, New York, Gwangju, Houston, etc. In 2013 he represented the UAE at the Venice Biennale with an immersive video installation entitled Walking on Water, curated by Reem Fadda, and in 2015 he showcased works from the Tongue series at 1980 – Today, curated by Hoor Al Qasimi.

Sigalit Landau - Salt Stalagmite #1 [Three Bridges]

Sigalit Landau, Salt Stalagmite #1 [Three Bridges], 2021

b. 1969, Israel

Lives and works in Tel Aviv, Israel

For over fifteen years, the Dead Sea has been a source of inspiration and a laboratory for Sigalit Landau’s video works, photographic series, and salt sculptures. Relying on her unique, innovative use of Dead Sea minerals, as manifested in so many of her physical works over the years, Salt Stalagmite #1 [Three Bridges], derives from Landau’s original idea of building a floating salt bridge over the Dead Sea to connect Israel, the Palestinian Authority, and Jordan. A symbol of hope and collaboration in the Middle East, this beautiful poetic utopian idea, conceived in 2010 and nourished by a wild political imagination, is yet to be realized on site. In its current AR manifestation, the work combines a tall salt stalagmite and a set of three salt bridges, offering viewers endless routes of exploration around the work and inside its hidden creeks. It touches on the notion of the bridge as a means of passage, a medium connecting people, cultures, and languages, and activating peace.

Sigalit Landau first came to international attention when she participated in Documenta X, Kassel in 1997. Over the past two decades, she has had numerous exhibitions in leading venues around the world, including KW, Berlin; MoMA, New York; the Israeli Pavilion at the 54th Venice Biennale; SCAD Museum of Art, Savannah, Georgia; and MACBA Museu d’Art Contemporani de Barcelona.

Daito Manabe Morphecore Prototype AR, 2021

Daito Manabe, Morphecore Prototype AR, 2021

b. 1976, Japan

Lives and works in Tokyo, Japan

Daito Manabe’s work presents an endlessly dancing digital figure, continuously morphing into new shapes, moving beyond any logic of physics or laws of the universe. Extracted from MRI scans of the artist’s brain, raw brainwave data is translated into digital movement that manipulates and choreographs Manabe’s 3D-scanned human body, alongside visual noises and glitches generated by distracting thoughts in the brain. The work thus presents a new potential relation between the brain and the body, emphasizing the ability of the mind to move into the infinite, while the body is still bound to physical limitations of motion, gravity, volume, shape, and form.

Daito Manabe is an artist, programmer, and DJ. His works branch into a variety of fields and take a new approach to everyday materials and phenomena. His practice is informed by careful observation and a quest to discover and elucidate the essential potentialities inherent to the human body, data, programming, computers, and other phenomena, thus probing the interrelations and boundaries delineating the analog and the digital, the real and the virtual.

Sarah Meyohas, Dawn Chorus, 2021

Sarah Meyohas, Dawn Chorus, 2021

b. 1991, USA

Lives and works in New York City, USA

In Sarah Meyohas’s work a player piano is set in the open garden, while birds fluttering around it seem to trigger a series of musical phrases with each moment of contact. Watercolors bloom across the surface of the piano, visualizing the movement of the birds as well as the sound waves that emanate from the vibrating strings. The viewer is initially triggered by the appearance of a single bird as an invitation to follow through and reveal the full work – a musical performance orchestrated by the seemingly uncultured.

Meyohas centers her practice within emerging technologies. Working in media ranging from cryptocurrency to augmented reality, she enlists the natural world as a reference, network as medium, and the specular as a mode of contemplation. By merging traditional mythologies and clichéd objects of beauty with contemporary digital media, Meyohas enacts a visual language for the systems, algorithms, and technologies that influence our daily lives.

Sarah Meyohas has exhibited her work internationally, with solo exhibitions in New York at Red Bull Arts and 303 Gallery. Her work has traveled to institutions, including the Barbican, London; Jameel Arts Centre, Dubai; Ming Contemporary Art Museum, Shanghai; Disjecta Contemporary Art Center, Portland; and the New Museum, New York.

Mel O'Callaghan, Pneuma, 2021

Mel O'Callaghan, Pneuma, 2021

b. 1975, Australia

Lives and works in Paris, France, and Sydney, Australia

Pneuma is an ancient Greek word for breath, spirit, or soul. Mel O’Callaghan’s work interlaces these meanings and invites the viewer to not only observe the work, but also engage with it and take part in a ritual process based on breathing. Walking toward a shimmering portal, viewers cross its threshold into a sphere of increasing color, light, and sound mutations in which the sound of breathing is heard, as if penetrating it from the outside, blurring the boundaries of life and non-life, organic and inorganic. With each breath, faster and deeper, the viewer gradually attains an altered state of consciousness where the body becomes a site of revelation, transcending thresholds to see what lies beyond physical and psychological limitations. Through this work and previous breathing works, O’Callaghan explores the ways trance states can be achieved based on breathing, rhythmic sound, and altered posture. O’Callaghan’s series of breath works was developed in collaboration with Sabine Rittner, Institute of Medical Psychology, University of Heidelberg, Germany.

O’Callaghan’s works explore human behavior and psychology in relation to notions of resistance, endurance, and transformation. Her videos, performances, installations, and paintings depict bodies pushed to the limit. Here and in much of her work, the human body is a site of agency and resilience through which she investigates individual and collective freedom. Recent solo exhibitions include UQ Art Museum, Brisbane; Artspace, Sydney; Palais de Tokyo, Paris; NGV, Melbourne; Casa-Museu Medeiros e Almeida, Lisbon; The Art Gallery of New South Wales, Sydney; and the Center for Contemporary Arts, Prague.

Anamazon (Limb), Pamela Rosenkranz

Pamela Rosenkranz, Anamazon (Limb), 2021

b. 1979, Switzerland

Lives and works in Zurich, Switzerland

In her works, Pamela Rosenkranz investigates transitions from the natural to the artificial, dissolving their distinctiveness with reciprocal copying strategies. Anamazon (Limb) appears in a cacophony of sounds from the Amazon in a seemingly natural environment. Pulsating waves run through the branch as if it were an organ pumping blood through its capillaries while a sticky green fluid oozes from its wounded broken edge. The use of the phosphorous green (derived from the RGB color model) as well as the intertwining of the botanic and the organic lends the branch a futuristic character, and raises a question regarding the larger entity from which this branch or limb originates, and the possibility of chlorocruorin* running through its veins.

Like the microbiome in the human body, whose multi-branched mode of action remains largely unexplored, the myriad connections and interactions of plant and fungal systems in the Amazon, for example, are yet to be fully recognized and described. Anamazon (Limb) appears as an extraction from an ecosystem that can only exist as far as the human imagination can reach.

* Chlorocruorin is a dichroic red-green respiratory protein, chemically similar to hemoglobin, and is only found dissolved in the blood of certain annelids.

Pamela Rosenkranz has had solo exhibitions at Kunsthaus Bregenz; Kreuzgang Fraumünster, Zurich; GAMeC, Bergamo; Fondazione Prada, Milan; Kunsthalle Basel; Centre d’Art Contemporain, Geneva; and the Swiss Institute, Venice, among others. She has participated in several major international group exhibitions, including the Okayama Art Summit and the 15th Biennale de Lyon. In 2015, her project Our Product was selected for the Swiss Pavilion at the 56th Venice Biennale.

Timur Si-Qin Biome Gateway, 2021

Timur Si-Qin, Biome Gateway, 2021

b. 1984, Germany

Lives and works in New York City, USA

Timur Si-Qin’s work takes form through diverse media and creates a new kind of environmental art. It challenges common notions of organic vs synthetic, natural vs cultural, human vs nonhuman, and other dualities at the heart of Western consciousness.

Si-Qin’s work in the exhibition presents a temple cave that connects the biotopes and organisms of the botanical gardens to a parallel landscape. Through a portal within the temple, the viewer is invited to enter a virtual sacred locus of contemplation.

The work is part of Si-Qin’s long-term meta-project New Peace – a proposal introducing a new secular faith in the face of climate change, global pandemics, and biodiversity collapse. Drawing on the concept of religions as an adaptive system of meaning for collective action, New Peace recognizes the central spiritual value of nature, and states that only through this type of deep cultural shift, the impacts of climate change may be mitigated.

Timur Si-Qin is a New York-based artist of German and Mongolian-Chinese descent who grew up in Berlin, Beijing, and in the American Southwest. Recent exhibitions include Von Ammon Co., Washington D.C.; Riga International Biennial of Contemporary Art 2; the 2019 Asian Art Biennale, Bangladesh; the 5th Ural Industrial Biennial of Contemporary Art; UCCA, Beidaihe; Spazio Maiocchi, Milan; The High Line, New York; and Magician Space, Beijing.

Water Serpent, Jacob Kudsk Steensen

Jakob Kudsk Steensen, Water Serpent, 2021

b. 1987, Denmark

Lives and works in Berlin, Germany

Jakob Kudsk Steensen’s work revolves around a 3D scanned cactus organ, a dried out branch the artist documented during a week-long desert trip in California. Drained of water, the cactus reveals its internal infrastructure, a rhizome that lends it its idiosyncratic survival qualities. Blurring inside and outside, botanic and organic, the viewer can explore the cactus from up close, and reveal a serpent swirling round it, its eyes following the viewer.

Steensen’s work aims to revive mythologies centered on snakes and deserts as positive spirits and omens of life, rather than a symbol of toxicity and death.

Jakob Kudsk Steensen was the inaugural recipient of the Serpentine Galleries’ Augmented Architecture Commission, and has recently exhibited internationally at the Venice Biennale; PinchukArtCentre, Ukraine; MATADERO Madrid; Tranen Center for Contemporary Art, Denmark; Mac Lyon; Pylon-Hub; SXSW; BRIC Brooklyn; the 5th Trondheim Biennale for Art and Technology; Carnegie Museum of Art, Pittsburgh; MAXXI Rome; and FRIEZE London, among other institutions and festivals.

What is augmented reality (AR)?

Augmented reality, or AR, refers to any technology that ‘augments’ or adds to the user’s view (and in some cases auditory perception) of their environment. Usually, digital information is super imposed over an existing real-world environment and is fixed in one place as the user moves around it or moves their device around it. AR is not a simulation of reality – instead, it integrates and introduces something unreal into the real world, adding to the user’s perception.

How it works

At RBG, visitors connect with Seeing the Invisible through their smartphone or tablet by downloading the app (available in the Apple App Store or Google Play) designed for an engaging exhibition experience. Using the app interface, visitors encounter 13 unique and interactive artworks dotting Hendrie Park’s landscape.

Visitors can snap photos engaging with larger-than-life, moving and interactive artwork that they can virtually walk through, while plugging into an audio component that amplifies the artistic experience.

How do I use the app?

Discover artworks via an in-app map and notifications as you near an artwork site. Additional instructions are provided when the app is opened. AR apps require significant battery use; arriving with a full battery charge is recommended, and portable batteries are encouraged.

For the best experience, visitors are encouraged to do the following before you visit:

• Download the app at home (Seeing the Invisible app is available for download through the Apple App Store or Google Play.)
• Charge their device and bring a portable battery if they have one
• Bring headphones (many of the artworks feature a soundscape that you don’t want to miss!)
• Allow the app to access the phone’s camera and microphone

What devices are compatible with the app?

The app makes use of Augmented Reality technology and high-end 3D graphics. It is because of this that it can only work on the following devices:

  • iPhone X or above.
  • An equivalent of Samsung Galaxy S9 or above.
  • The app works with tablets of similar specs. Only cellular capable iPad models work with the app due to the built in GPS receiver.
  • Additional device compatibility list

* Apple devices require a software version of IOS 11 and above.

* Android devices require a software version of Android 9.0 (Pie \ API 28) and above.

Seeing the Invisible is available for download through the Apple App Store or Google Play.

Is the app free?

Yes, it is available for free via the Apple App Store and Google Play. The app may also be downloaded onsite via mobile data, though since it is large, downloading it at home is recommended. As Seeing the Invisible is technologically demanding, the app is only compatible with devices that are less than 3 years old.

The app is 1.6GB. It is recommended that devices have a minimum of 4GB free memory.

How to Calibrate Your GPS Accuracy

GPS accuracy can vary depending the device you are on. If your dot appears off the route, try to wave your phone in a figure 8 motion to recalibrate your location.

WATCH: How To Calibrate Compass In Mobile Devices

Is the experience interactive?

Yes—using the app, artworks can be moved within their sites and “placed” where you would like to see them. Many of the artworks can also be walked through, but be aware of plant life and other visitors when exploring. Some works incorporate audio; headphones are recommended.

Will I be able to take selfies/pictures of the exhibition?

You will be able to take pictures of the exhibition using your phone or handheld device through the screenshot feature. Due to the nature of the AR technology, rather than taking a selfie, we recommend that someone else hold the device to take pictures of you with the artwork. Make sure to share your experience and tag #RBGInvisible in your photos and videos!

How do I prepare for my visit?

Prior to your visit we ask that you download the app in advance. Seeing the Invisible is available for download through the Apple App Store or Google Play. Please ensure you arrive with a fully charged device. We will have some chargers onsite but can not predict wait times to use them. A number of the art “installations” include a soundscape. We recommend you bring your own headphones, however Shop @ the Gardens will be selling them for $15 each.

Do I need to wear a mask?

As we welcome our community and visitors back to experience the beauty of Royal Botanical Gardens’ (RBG), we are making every effort to help ensure your visit is enjoyable, entertaining and, above all, safe.

Please observe all markers and one-way indicators upon arrival and stick with your group for the duration of your visit, following physical distancing guidelines.

What do I do if I feel ill?

As part of our commitment and shared responsibility for the health and safety of our guests, staff and volunteers, we ask that guests perform a self assessment to help reduce the spread of COVID – 19 prior to your visit. Should you feel ill please stay home and contact your health care provider. Your tickets can be transferred to other family members or friends (no transfer fee required).
