Remembering and forgetting, blossoming and withering, becoming and being – Hartung & Trenz explore the diversity of temporal experience through text, light and sound. Along the avenue of Eggenberg Palace Park, ‘Spaces of Time’ unfolds as a large-scale artwork that conceives of time not as a linear sequence, but as a personal experience of walking and seeing. The message emerges through movement, as the projected texts change with every step. Like blank lines, the spaces in between provide time and room to reflect on what has been seen. Parallel to these word-images, acoustic spaces emerge, the sound of which changes depending on one’s location. And last but not least, nature is also an essential component of the installation: the avenue, with its clusters of trees, and the surrounding flora and fauna enrich the artistic spaces with further movement and depth through their own vitality.

Biography
Over the course of their more than 20-year collaboration, Detlef Hartung and Georg Trenz have developed their own form of artistic expression, through which they transform texts into striking images. Concrete language becomes pictorial symbols, both in content and form. The resulting word-images create expansive image-text spaces that enter into a dialogue with the real, three-dimensional spaces onto which they are projected.

How do we view a historic building today that was created under entirely different social conditions? What significance does this encounter between different eras hold for us? Daniel Rossa’s art navigates the tension between preservation and transformation – as is the case with his façade projection at Eggenberg Palace. Through light, colour and movement, an image emerges that neither stages nor creates an illusion of the site, but rather renders it visible and interpretable in a new way.
Starting from a precise digital reconstruction, the German media artist examines the palace in terms of its form, proportions and symbolism, and develops a contemporary language from this. In this language, the original order dissolves; images of the Baroque interior are turned inside out, only to be progressively abstracted further by the movements of a dancer. From the Baroque structures emerges a contemporary perspective on the building, one that seeks, above all, a dialogue between history and the present.

Biography
Daniel Rossa is a German media artist whose work emerges at the intersection of architecture, light, and digital media. He studied at the Bauhaus University in Weimar, whose interdisciplinary approach—combining art, design, and technology—continues to shape his artistic practice to this day.
At the heart of his work is an exploration of architecture as a living medium. For his site-specific projections, Rossa develops precise digital models of historical and contemporary buildings, which he transforms into new visual narratives through light, movement, and algorithmic processes. His works examine the relationship between physical space and digital perception, moving between documentary precision and abstract transformation.
Daniel Rossa’s works have been presented internationally, including at the Sydney Opera House, the Saatchi Gallery in London, and the Elbphilharmonie in Hamburg, as well as at numerous international light art and media art festivals. For his work, he has received awards such as a Cannes Design Lion and the German Lighting Design Award.
For KLANGLICHT 2026, Daniel Rossa is developing “Kadenzen,” a work conceived specifically for the façade of Eggenberg Palace, which places the historic building in a dialogue between Baroque order and contemporary visual language.

They stretch out their long, soft arms – almost as if they wanted to touch people. And it is not uncommon for this gesture to turn into an embrace: people stroll through these ‘Whispering Mountains’ by the Australian studio ENESS, pause for a moment and long to be close to them. Perhaps it is down to their form, which combines the artificial and the natural in a unique way. Although shaped like a natural landscape familiar to us, these mountains are enriched with digital textures and a digital life of their own. Each mountain whispers brief thoughts to visitors: messages developed by artificial intelligence that invite reflection.
In this way, the ‘Whispering Mountains’ create conscious moments of slowness in an age of constant acceleration. Just as in real mountains, where people forget the time to find peace and clarity, this artwork also offers moments in which time is not measured but consciously experienced.

Biography
ENESS was founded in 1997 and is a multi-award-winning art and technology studio. The team creates temporary and permanent interactive art in public spaces that combines various disciplines such as sculpture, textile art, design, programming, music, and storytelling. At the heart of all of ENESS’s work is the connection across generations. As pioneers of new media art, the collective believes in the power of art in everyday life to spark the imagination and bring joy, happiness, and beauty to unexpected places—transformative experiences that change lives.

Inspired by historical planetariums, the Dutch artist Robin Beekman measures time in a new way in the castle chapel of Eggenberg Castle: ‘Continuum’ counts the seconds since the artwork’s creation, thereby following its own ‘biological clock’. However, the seconds in the work are not all the same; in the randomness of this timekeeping, one second is slower, another faster. Twenty-four specially developed lights react to these uneven units of time and produce an equally random, constantly changing pattern of light.
Far removed from our familiar 24-hour rhythm, ‘Continuum’ is a unique constellation of the present: when time begins and when it ends recedes into the background. Rather, it is a sense of time all of its own – and at the same time a sense of endlessness – that arises with this work.

Scents evoke memories – and can transport us to other places, to other times. A prime example of this is Muhammad Aszizi and the scent of his Syrian homeland, which reminds him of the landscape of his childhood, the plants, the earth and the atmosphere. The story of this refugee lies at the heart of Helga Griffiths’ project ‘Migratory Senses’, which focuses on smell as the sense capable of immediately evoking memories within us.
This fusion of art and neuroscience illustrates something both ordinary and extraordinary: time here is not linear, but is stored within us as a combination of perception, emotion and memory, and can be revived at any moment – for example, through a scent. In this way, ‘Migratory Senses’ tells not only of flight and home, but also of the universal, deeply human longing for places that have shaped us.

Biography
Helga Griffiths works at the intersection of art and science. In her multimedia installations—which engage the senses—she explores biological processes, human perception, and the way the brain processes information, emotions, and memories. In doing so, she translates scientific findings into poetic spaces of experience, making visible or tangible what often eludes immediate perception.
A particular focus of her artistic work is the sense of smell and its close connection to memory. Griffiths views scents as carriers of personal and collective memories: they can bring past places, people, and phases of life back to the present in an instant. Her works thus challenge linear conceptions of time and make memory tangible as a physical, emotional experience.

How does light change with the passage of time? What we cannot perceive with our eyes – or see only as a snapshot – is made visible by Inge Dick’s artwork ‘jahres licht weiss’. Over the course of several years, the artist captured the changing play of light’s colours in a white room. Her interest lay primarily in the subtle nuances determined by the natural changes in the seasons.
The resulting large-format film stills, on display in the Planetarium Hall at Eggenberg Palace, are precisely constructed compositions of spring, summer, autumn and winter. The cycle is not merely a comparison of colour spectra, but visualises what we ourselves feel: that every season has its own light and, with it, its own atmosphere.
In the context of the space, the installation takes on further significance: the hall, with its Baroque imagery, depicts a cosmological system featuring zodiac signs, cardinal points, days and nights. With its seasons, ‘jahres licht weiss’ subtly expands the existing space.

Biography
Inge Dick studied at the University of Applied Arts Vienna and began her artistic career as a painter. Through the photographic documentation of her own paintings, she discovered photography—and with it, the theme that continues to shape her work to this day: light as an independent creative medium.
In experimental photographic works, large-format Polaroids, and films, Inge Dick explores the interplay between light, color, space, and time. Her focus is not on spectacular events, but on the subtlest changes in natural light: the transition from the first glow of dawn to daylight, atmospheric shifts over the course of a day, or the varying moods of light throughout the seasons. She does not view color as a static quantity, but as the result of the interplay between material and light.
A defining feature of her work is her consistent observation of the barely perceptible. Through photographic and cinematic magnification, she makes fleeting moments of light visible and sensitizes the viewer to changes that often go unnoticed in everyday life. Her minimalist works deliberately forgo additional media effects and unfold their impact solely through light, space, and time.

Knowledge is valid only until it is disproved. The astronomical symbolism at Eggenberg Palace illustrates this, as does the work of Miriam Hamann, whose installation ‘Planet 9’ creates a dialogue between the palace’s historical worldviews and contemporary ones.
The starting point is the hypothetical Planet 9 on the edge of our solar system. No telescope has yet been able to image it. Current research deduces its existence solely from mathematical calculations and the unusual orbits of other objects. The fact that science operates here not on the basis of certainty but of probability forms the core of Hamann’s work. The focus is therefore on the background to this potential discovery rather than on the planet itself: the artist transforms astronomical diagrams into a minimalist yet poetic light sculpture that allows the scientific process of discovery to be experienced spatially. In this way, ‘Planet 9’ tells not only of the evolution of knowledge over time, but also of the willingness to continually question established ideas.

Biography
Miriam Hamann, whose works straddle the line between sculpture and installation, combines scientific abstraction with visual clarity.
In her installations and sculptures, Miriam Hamann (*1986, Wels) explores scientific phenomena and their influence on our understanding of the world. By questioning their validity, she reveals systems of order as malleable constructs and asks what happens when we let go of the illusion of complete control. Her works open up a space for reflection at the intersection of science, philosophy, and the often intangible dimensions of our reality.

Stones, fragments and relics in the Lapidarium in the grounds of Eggenberg Palace transport visitors to a time long past. ‘ABIOSIS’ by Heleen Blanken builds on this look back: inspired by the speculative ‘primordial soup’, the installation turns back the clock to a moment of becoming, when life first emerged from inanimate matter. Blanken’s sculptures are unmistakably mechanical, yet they appear to be breathing. This creates a connection between the inanimate and the animate, adding a temporal dimension to the context of the Lapidarium: the beginning.
The fact that this contemporary element, situated within the historic complex, also creates scope for new interpretations is entirely intentional: at the interface between technology and the organism, the beginning of new life can refer not only to a moment in the past, but also to a speculative future of artificial life forms.

Biography
Heleen Blanken is an interdisciplinary artist based in Amsterdam who works at the intersection of installation art, new media, film, set design, and sculpture.
She studied fine arts at the Gerrit Rietveld Academy. In her artistic practice, she explores the complex relationship between humans and nature and examines how we perceive and interact with nature. By addressing traditional dichotomies such as organic versus artificial and analog versus digital, her work raises questions about our understanding of the natural environment and crafts speculative, futuristic narratives.
Heleen’s works have been shown in exhibitions worldwide, including at the Nxt Museum, the Stedelijk Museum Amsterdam, the
Kunstkerk Dordrecht, the Stedelijk Museum Schiedam, the Floriade World Expo 2022, the Gropius Bau Berlin, the Ron Mandos Gallery, the Musée d’art Contemporain, and Ars Electronica. She has collaborated with institutions such as the Naturalis Biodiversity Center in Leiden, the Museum für Naturkunde in Berlin, and the Institute for Geosciences in Utrecht.

Javier Riera always responds to the location of his work: to the architecture and its history, and to nature. In Eggenberg Palace Park, visitors encounter two large-scale light projections by the Spanish artist, which harmonise seemingly contradictory impressions: they are monumental and surprising, yet at the same time calm, almost meditative, and despite their sheer size, they blend seamlessly into their surroundings. The luminous, geometric forms are not foreign elements, but appear almost natural – like structures that had previously remained hidden from view and are now revealed by the light.
The light installations draw on both the park, which evolved from a Baroque to a Romantic garden, and the palace with its astronomical orientation. In this way, ‘ ’, the installation deliberately alludes to the mutability of human thought, scientific knowledge and historical conceptions of nature and the cosmos.

Biography
Javier Riera is known for his land art and projection-based works, which explore the intersection between geometry and nature—a relationship that lends his installations a meditative quality. His goal is to expand the viewer’s perception toward an experience of visibility and connection with the energy of nature. His works have been shown at numerous light art festivals worldwide, exhibited at leading museums such as the Museo Reina Sofía and MUSAC in Spain, and are part of major public and private collections.

Slowly yet inexorably, the historic pavilion in Eggenberg Palace Park is undergoing an apparent transformation. Its distinctive architecture, complete with the impressive ceiling painting, merges with the surrounding natural landscape to form the art project ‘Floral Forest’ by Joschua Hohenbrink: abstract Rococo ornaments grow into the pavilion like organic life, climbing up its walls and giving rise to a poetic, sensuous forest. Woven into this digital tapestry are live analogue images of a raven’s feather – the heraldic animal of the Eggenberg family – creating a work of art that never looks the same – at no hour, on no day.
With ‘Floral Forest’, the pavilion in the castle grounds is expanded without actually changing. Like an echo from the past, light and sound spread throughout it, offering a new perspective on this historic site.

The sound accompanying the video mapping is by sound designer Gregor Schmitz, who previously provided the soundscape for Olafur Eliasson’s ‘Eye See You’ project at KLANGLICHT 2025.
The project is being realised as part of the “KLANGLICHT Young Masters” programme.

When we gaze up at the starry sky, we know that the light reaching our eyes has been travelling for millions of years. This phenomenon also applies – and we are far less aware of this – to every other form of light. Even when light travels only from a nearby object to our eyes, every glance reveals a moment that has, in fact, already passed.
The large-scale installation ‘All the light you see’ plays with this very passage of time. In a three-second rhythm – the duration that many cultures perceive as a ‘moment’ – words fade in and out, altering their collective meaning. This interplay of language, light and darkness makes the present moment immediately tangible. The realisation that every glance is a glimpse into the past becomes all the more evident within the historical context of Eggenberg Palace.
At the same time, the work’s message also points to the future, for with every moment new light emerges and with it new possibilities. ‘All the light you see’ thus becomes a poetic reflection on transience, perception and hope.

Biography
Alicia Eggert (b. 1981, USA) is an American conceptual artist and sculptor whose interdisciplinary works explore the relationships between language, light, and time. Inspired by physics and philosophy, she translates abstract concepts into large-scale installations that combine scientific insights with poetic experience. She gained international recognition in particular for her animated neon works, in which language takes on an additional layer of meaning through movement, rhythm, and light.
With her installation “All the Light You See,” Alicia Eggert transforms a physical fact into a poetic reflection on perception, transience, and the present moment—themes that are directly linked to the curatorial theme of “time.”

‘The Self at 50 Hertz’ is like a stenographer who records and condenses everything that happens: a carousel with twelve symmetrical mirrors reflects the room and, thanks to its high rotation frequency of up to 50 hertz, combines all the mirror images into a single image of the surroundings. To achieve this, the Dutch artist Omer van Soldt drew inspiration from early optical illusions and animation techniques, translating their concept into a contemporary context. In doing so, the work mirrors its own exhibition venue not only literally but also figuratively: the Baroque Eggenberg Palace set amidst our present day.
As viewers approach the installation, their presence is also captured as a reflection, integrated into the generated image and thus becomes one with the historic space. This participatory element is not merely playful in nature; it also invites viewers to reflect on themselves as part of their own environment.

Biography
Omer van Soldt is an artist, author, filmmaker, and curator whose interdisciplinary practice explores communication, language, and the mechanisms through which meaning is constructed and exchanged. In his work—which spans performance, installation, film, theater, and research-based projects—he examines both the possibilities and the failures of communication in contemporary society.
Van Soldt moves fluidly between gallery spaces, theater productions, festivals, and collaborative research environments. In his work, he frequently explores how artistic forms can function as alternative languages to create new forms of dialogue between artists, audiences, and public space.
He is currently affiliated with the ArtScience program in The Hague and is an active member of interdisciplinary initiatives that bring together visual art, performance, light, and sound.

The world can also be viewed as if through a prism: not in one direction, but in several at once. Using light and sound, students from FH Joanneum explore various themes from the world of Eggenberg Palace and incorporate their individual works into the overarching project ‘Prism’. The various fields of study – Interaction, Sound and Media Design – form the basis for the wide range of artistic works, which explore themes such as mythology, astrology and polyrhythms.
The resulting installation is not only open to the public; with every step, the relationship between light, sound and the audience changes. The result is a multi-layered spectrum of movement, colours and sounds that constantly reconfigures itself depending on the viewer’s perspective.

The project was supervised by Astrid Drechsler, Daniel Fabry, Michael Kernbichler, Didi Mosbacher and Roman Pürcher.

Progress, consumption, decay – and ever-increasing energy consumption to sustain them. With her project ‘Energy in Time’, Zeineb Kaabi explores the commercialisation of products and the associated consumption of resources. For her video installation, the Tunisian artist condenses archive footage and historical adverts into a visually striking kaleidoscope. The rapid montage of the material, repetitions and superimpositions, combined with deliberate colouring and additional image generation, convey a sense of unease, restlessness and even overwhelm.
The destructive cycle of creation, exploitation and depletion is thus translated into a work of art that, through the lens of the past, poses questions about the present and the future: How do our own consumption patterns and the systems behind them take shape today? And what impact will they have on tomorrow?

Curated by Zalán Szakács.

Biography

FRACTAL CODE transforms space into an immersive interplay of light, shadow and projected fractals. Fractals are the building blocks of many patterns found in nature. What begins as a coherent structure is progressively reduced: form becomes grid, grid becomes pixel, pixel becomes isolated fragment. Through the layering of transparent planes, a state emerges between visibility and dissolution.
The installation explores how meaning is created when an image can no longer be perceived as a whole, but only through its individual components. It is light that reunites the scattered elements. Within the projected shadow, the fragments aggregate into a new entity, revealing that the whole is greater than the sum of its parts.
The underlying fractal pattern was developed in collaboration with 13&9 Design and Professor Richard Taylor (University of Oregon and Fractals Research). Research has shown that certain fractal patterns can trigger a natural relaxation response, helping to reduce stress and support well-being. The result is a space that challenges perception while simultaneously offering moments of calm, contemplation and regeneration.
