An interactive media installation in public space. Premiere was at the Klanglichtfestival in Graz October 25 – 27, 2023 in collaboration with Michael Strohmann, who designed the sounds and interactive technology. 18 LED RGB spots, 3 LED scanners, 8 loudspeakers, a computer, two video cameras and a lot of cables. The realization was made possible with the help of Holger Lang, who made his Sternstudio gallery available to me for the weeks-long preparation phase.

The space: a 13 meter long passageway at the Karmeliterplatz in Graz at the foot of the Schloßberg. Lightinstallation: 13 different impressionistic color presets slowly alternate with each other. The low-angle position of the LED spots create big shadows of the passers-by on the opposite wall. Additional spots in different colors create more colored shadows.Three scanner project moving spots on the ceiling in corresponding colors, now and then they meet in the middle of the opposite wall waiting to be „touched“. This „touch“ then triggers their upward movement. At the same moment, the flapping of birds‘ wings can be heard. The soundscape consists of frog, insect and owl voices that react to the presence of people.

– a video- and lightinstallation by MUTUAL LOOP (Holger Lang and Martina Tritthart) from May to June 2022 in the the ‚Red Carpet Showroom‘ in public space at Karlsplatz Vienna featured by Künstlerhaus.

With the help of Bernhard Meißnitzer and the team of Künstlerhaus: Pete Gmachl, Vinzent Cibulka and Gerald Roßbacher.

Trains, buses, cars, bicycles and pedestrians meet over several levels at one of Vienna’s busiest transport hubs. In addition, trees, meadows, flower beds and bodies of water invite you to linger, rest and dream. The contrast between urban movement and the relaxing power of nature can hardly be greater than in this place. Video loops on spatially arranged screens and a slowly running light sequence pick up on these opposites and continue them reflected in the showroom. Vehicles move through the city in patterns that always appear to be the same, along lanes and lane markings. Bushes and trees, in turn, create counterpoints in the visual composition. A red line not only leads through the underpass, it also connects the street with a virtual undergrowth in which a stylized jungle also dissolves into shapes and structures. The question of a confrontation between the challenges of traffic in the urban environment and nature itself, as a synonym for a possible different way to each other, is discussed and negotiated aesthetically in this work. However, it is not about presenting a simplified position on either city or country, on traffic or forest, but about presenting what connects and complements each other.


A 3 channel -videoinstallation by MUTUAL LOOP (Holger Lang and Martina Tritthart) for „Fission, The New Wave of International Digital Art“ exhibition from 30 April – 31 August 2022 in Guizhou Provincial Museum, Guanshanhu District, Guiyang, Guizhou, China

curated by Birgitta Hosea

14 minutes loop of 3 video & 6 Audio channels


was a participatory project by MUTUAL LOOP (Holger Land, Martina Tritthart) including two guided tours in public space in Vienna with 12 visitors on November 15, 2021 during the VIENNA ART WEEK. The route and its stations starting from Sternstudio Gallery in Vienna: Mayergasse, Czerningasse, Passage Czerningasse 7-9, Praterstraße, Rotensterngasse, Weintraubengasse, Renzhof, Zirkusgasse, Novaragasse, Praterstraße, Mayergasse

The tour included an examination of the cultural history of the 2nd district around Praterstraße and visits to artistic trades. In the Sternstudio gallery, pictures of the people named in the tour, historical events and buildings as well as specialist literature on them could be seen. In addition, the films presented during the tour could be seen again on a monitor.

In addition to a kind of double conference between the guest artist Anat Stainberg and organizer Martina Tritthart, the tour included a mobile projection unit with a projector and battery, as well as a small trolley operated by Holger Lang. For each of the alleys, streets and squares mentioned above, there were detailed reports and stories about well-known personalities who used to live here, were born or died here. Above all, the lively culture and circus scene in the 19th century around the Carlstheater and the Renz circus as well as numerous smaller theatres, variety shows and cafés was the subject of these tours. At selected stations, short animated films were projected onto the facades of houses, the content of which was related to the respective location. The participants received laser pointers and instructions to trace certain images from memory. In addition to the conversations, further communicative dynamics emerged. The discussions were then continued in depth in the Sternstudio gallery.


VORTEX is a tunnel of vibrating lines within an industrial space that can evoke dynamic work processes and the belief in progress that is often manifested in them, but at the same time with a chaotic weave of lines, it can also call them into question. The path along the ribbons leads into the unknown and undiscovered. The whole picture will never be fully visible, an uncertainty in space always remains. The light, which is itself invisible, travels along the rays, which themselves are not luminous.  We used 2 kilometers of rubber bands for this multimedia installation including light and sound. VORTEX was part of the exhibition HOUSE OF LOSING CONTROL at the Vienna ART week in November 2021. VORTEX is a project by mutual loop (Martina Tritthart & Holger Lang)


Right above the center of the labyrinth in the City Park in Skopje North-Macedonia raises BREATHING STAR, a dynamic light and space-installation. The size of the structure consisting of about 400 strings is 16 x 18 meter and 5 meter high. Together with a sophisticated light-choreography and a surround sound designed for the unique spatial situation the artwork changes its appearance, creating an oscillating, pulsating, vivid atmosphere. It is highly recommended to enter the structure. There is a walkthrough to experience the artwork from the inside. Beyond the experience of the artwork itself we want to draw the attention of the viewers to the night sky above. Breathing STAR becomes a window on the universe. BREATHING STAR was part of the international lightfestival „Skopje Light district“ in September 2021. BREATHING STAR is a project by mutual loop (Martina Tritthart & Holger Lang)


A participatory light- and video intervention : Drawing an outline, a figure, a shape, a contour with light, describing a relationship between architecture, the surroundings and people in the context of this event with the possibility to interact. A performance during „Der blöde dritte Mittwoch“ curated by Anat Stainberg in the Halle of Steinergasse 8, June 16th 2021. Duration 30 min

From line to surface to space, here and now and in process and in three chapters:

1. Sitespecific film inscribed in space

2. Audioreactive interactive animation in space

3. waving good-bye with translucent foil, wind and pulsating lights


IN-SIDE-OUT is part of the project SOLARIS curated by Mehr Licht in Graz, Schlossbergstollen-Galerie. Based on the novel by Stanislav Lem „In-Side-Out“ questions the alien in ourselve. „In-Side-Out“ is a dynamic light installation that stages the oscillations of light and sound. IN-SIDE-OUT, dimension 3 x 2,5 x 30 meter, is a project by mutual loop (Martina Tritthart & Holger Lang) at the Schlossbergstollen-Galerie GRAZ,  July 31st 2020 – March 2021

A tube of vibrating lines within a tunnel that has no visible end is a metaphor for diving into the ocean of the unconscious, into the secrets of our own identity, in which we become strange and eerie to ourselves. The path into the unknown and unexplored within our souls can only be taken slowly. The whole picture will never be fully visible. Like a dark sun, the far end of the corridor reflects the transition into what is hidden inside the world that we know. Light and matter lead us into the depth of the mountain and at the same time into the depth of memories of our adventures, experiences and the impressions that we have gathered. We stretch a bright thread that can figuratively bring us from the underground back to the daylight of our consciousness. This connection builds the tunnel that links us with the hidden, with the darkness and the mysterious inside us.


Die Installation „Schleifensache II“ ist ein gemeinsames Projekt von Martina Tritthart und Holger Lang (Mutual Loop) für den ASIFAKEIL im Museumsquarier Wien, von 16. 6. – 17.7. 2020

Das Universum leuchtet aus seiner dunklen Ecke. Ein Winkel fällt in sich selbst zurück und schliesst einen Kreis an Mutationen, Variationen und Wandlungen. Über das sich spiegelnde und brechende Licht faltet sich ein konkreter Ort in eine Serie an flüchtigen Bildern und fliessenden Eindrücken. Abstrakte Muster tasten sich entlang der Grenzen des Projektionsraums. Schleifensache II ist die nächste Stufe einer Zusammenarbeit, in welcher intuitiv auf eine Raumsituation eingegangen wird.


CORONA-TIME: Due to the restrictions to prevent Covid19 I started working on a new piece, where my shirt was animated to become alive and found its place inside my sitespecific installation TOPOS at ASIFAKEIL, MQ Vienna May 10th – June 16th 2020 (an almost public space inside the Museumsquartier)

Do (not)touch me ©Martina Tritthart 2020


In der ortsspezifischen Arbeit TOPOS wird der vorhandene Ort und seine Erscheinung mit minimalen subversiven Mitteln akzentuiert und verändert: Man sieht nichts, aber man sieht es, wenn man sich als Betrachter*in auf den Ort einlässt. Dann erregen Phänomene der Bewegung die Aufmerksamkeit. Der Ort erscheint in oszillierenden Raumbildern und reflektiert gleichzeitig die subjektive Befindlichkeit.

Asifakeil, Q21, Museumsquartier, 9. März – 13.Mai 2020

Topos: Das ist ein Ort an dem ich mich befinde. Und weil ich hier bin, ist der Ort mein Befinden in einer bestimmten Situation, die man auch als Atmosphäre bezeichnen kann. Topos beschreibt in der philosophischen Phänomenologie den Raum der Anwesenheit im Unterschied zum metrischen Raum. In der Topologie wird die Orientierung nicht mit einem Koordinatensystem sondern vom eigenen Leib ausgehend mit der Wahrnehmung des Sichfindens in einer räumlichen Situation definiert. Die subjektive Situiertheit löst einen Wahrnehmungsprozess aus, der Phänomene sichtbar macht. Ein Phänomen ist etwas, das sich zeigt, etwas, das ins Bewusstsein dringt.

This building, or what is remaining of it, with its steel grid is reminding of the architectural period of Constructivism, which still has a presence in Jekaterinburg. When considering this viewing platform the „Wolkenbügel“ from 1925, El Lissitzkys so-called Cloud irons, comes to mind. For Holger Lang and Martina Tritthart this edifice can work as a silent observer of the history, of the arts, and of the city, collecting and condensing the hopes and dreams of the people. In the project of Mutual Loop this building will turn into „Sky-Lights“, simultaneously functioning as a beacon, as a horizontal lighthouse, and a spatial movie. The structure of the building becomes the structure of the film. White light turns into colors and vice versa, framed in a temporal and varying loop.The inside irradiates to the outside and the concrete turns abstract.

Licht selbst ist nicht sichtbar, es wird reflektiert, wenn es auf einen Körper fällt, selbst wenn es kleine Staub-Partikel sind, die dem Licht ein Volumen geben. Es entsteht ein Moment der Erhabenheit, der in jenen, die das ästhetische Lichtspiel beobachten, Assoziationen von Milchstraße oder Spiralnebeln hervorrufen. So wie die winzigen Staubpartikel der Lichtquelle zufliegen zu scheinen, so streben auch wir Menschen nach Ansehen, Ruhm und Glanz, die sich vielleicht einen kurzen Moment lang einstellen, bevor sie wieder verfliegen, wie Rauchwolken oder Nebelfetzen, und winzige glitzernde Teilchen zurück lassen, die mit der Zeit verblassen und als Staub herabfallen. Anat Stainberg und Martina Tritthart experimentieren mit Staub, Licht, Projektion, Körpereinsatz und Worten.

5 motorbetriebene dichroitische Gläser mit Steuerung, 6 PAR-Scheinwerfer, 1 Videoprojektion, 1 Audioinstallation, 1 Camera obscura, 1 Recycle-Mobile mit Kleiderbügeln und dichroitischen Gläsern

Die installative Arbeit von Martina Tritthart basiert auf den Grundprinzipien der Optik und der menschlichen Wahrnehmung, die sie in Relation zum jeweiligen vorhandenen architektonischen Raum immer wieder aufs neue infrage stellt. Die Werkschau „All the colours you like!“ präsentiert drei Lichtarbeiten, die die Phänomene Projektion & Schatten, Reflexion & Interferenz und Camera Obscura behandeln. Neben Licht- und Medienprojektoren verwandeln sich drehende dichroitische Gläser den Ausstellungsraum in einen immersiven Erlebnisraum.

durch gehend 28. – 30. Juni 2018

ist eine von Martina Tritthart konzipierte Lichtintervention für einen Fußgänger- und Radfahrerdurchgang am Wiener Praterstern. durch gehend ist Teil der Philomena Pratersternstunden 4/4 kuratiert von Christine Bruckbauer. Mit ihrer poetischen Lichtarbeit will die Künstlerin das mulmige Gefühl entschärfen, das an diesem Ort entstehen kann. Von manchen wird diese kurze, dunkle Gasse als besonders verunsichernd und beängstigend empfunden. Dem entgegen will Martina Tritthart mit ihrer Installation bei Passant_innen eine positive Raumerfahrung erzeugen. In der Unterführung am Praterstern projiziert die Künstlerin zwei sich überlagernde visuelle Ebenen, die bewegte Worte und Formen beinhalten. Die Texte nehmen einerseits Bezug auf die gegenwärtige Situation am Praterstern andererseits reflektieren sie Stimmungen und Gefühle. Lesbar werden sie innerhalb der von den Passant_innen generierten Schattenbilder. Im Spiel mit dem Licht ergeben sich immer wieder neue Text- und Form-Kombinationen. Zusätzlich wird der bespielte Raum durch die Durchgehenden laufend neu konstituiert. Die Passant_innen sind zugleich Rezipient und integrativer Teil der Neuformierungen.

Besten Dank an Christine Bruckbauer und Familie, Abdulrab Habibyar, Aline Lenzhofer, Holger Lang, Roman Bönsch, Patrick Timm !

mehr zu den Texten / Quellen und dem Nachfolge-Projekt City Light ….

durch gehend June 28 – 30 2018

is a light intervention designed by Martina Tritthart for a passageway at Vienna’s Praterstern. With her poetic light work, the artist wants to defuse the queasy feeling that this location may cause. For some this short dark alley may even be seen as an unsettling and scary place of fear. Antagonizing this, Tritthart wants to create a positive experience among the pedestrians at this site. Inside the underpass at Praterstern Martina Tritthart projects two overlapping animated visual levels, containing animated words and shapes. The texts refer on the one hand to the current situation – as it is experienced and described – on Praterstern, and on the other hand, reflect moods and feelings of visitors.
Separately they become readable through shadows, generated by those who pass by. The play with the light always results in new text-shape combinations. The existing space is permanently reconstituted through the participants and makes them simultaneously recipients and also an integrative part of the new formations.
