Physical Reality Devices I & II, for TRIALE „digital framework“ Gallmannsegg, 2022


Physical Reality Devices I & II are framing tools, touchable and usable art objects that suggest an intensification of the act of seeing and a questioning of one’s own perception. The user becomes a performer, examining they* real environment as if through VR glasses, which is recomposed in the devices. Inside Physical Reality Devices I & II the gaze is redirected and recomposed by mirrors. We see what would not be visible from one’s own point of view without these tools.

Feldmessung, trailer





„Feldmessung / Arpentage / Surveying” is a performative project that playfully questions measurement processes and highlights their possible inaccuracies and failures. In order to define spatial boundaries and explore certain laws of fundamental physics, the performers play with their own bodies as well as with working tools. Through acrobatic movements, tensions of ropes, experimentations with lights and the manipulations of objects, the performers develop their own method of measurement and take their audience into a world where science and poetry are intertwined.

Landing on Planet B
Lena Gätjens & Paul Pritz, Schlossbergstollen, Graz (AT), Solaris group show
kinetic, site-specific installation that reenacts the moment of discovery.
The cone of light travels through the space following a choreography that stages the careful scanning of an unknown place. The grazing light magnifies the details of the topography, projects them onto the surfaces of the room like a shadow play and frames fragments of the space. The idea of an understandable overall space fades into the background.

Lena Gätjens



Lena Gätjens works as a lighting, stage and costume designer for independent theatres and film productions, as well as lighting in architectural contexts. As a multidisciplinary (light) artist she works on site-specific installations, art-on-building projects and interventions in public space. Her installations and sculptures are often designed to be touchable or usable. The focus of the often collectively created works lies in the participatory, in the public space, in the intervention in everyday life.



The alternation of micro- and macro-view, which she has internalized as a stage designer, continues in her dealings with light and seeing. Her light installations and objects (often) move on a human scale, want to be approachable, remind us of something we know, or draw on fragments of everyday life.



To artistically fathom the interconnectedness of seeing, perceiving and light is usually the beginning of the site- or material-specific works. The starting point for her works is often an ephemeral moment of perception or seeing, a detail that she extracts and presents as an autonomous sculpture or installation. In reconciling the subjective with the views of others, we practice respect and recognition.The potential of art forms in public space is to affect the everyday life of those who pass by.





collective works



Lena Gätjens works as one 3 of 333 – a light art collective that creates art-in-public and art-in-architecture projects with both daylight and artificial light.



With Plus Ou Moins Cirque Productions (POMC) she develops since 2016 the site specific performance series UNMEASUREMENT.



As Jens of Horst-Jens Olé they sometimes (used to) appear with a mobile telephone booth in the public space that they set up and let it ring to provoke honest and truly anonymous conversations, the TELEFONZELLE.









The world is falling apart, so is my website. This is work-in-progress, I am working on reorganizing it together with schulergätjens.
