material messenger

29. June – 14. September 2025
Gruppenausstellung, RAUM SCHROTH im Museum Wilhelm Morgner, Soest

English, ‘material’ is both a thing and a quality. The exhibition at RAUM SCHROTH presents international works and artistic concepts that focus on the material itself and explore its elementary nature, characteristics and behaviour.

These reflections include, in particular, possibilities of the material that run counter to customary uses, as well as surprising properties that the material does not usually display. The basic material is extremely diverse, ranging from solid substances that are also used to produce goods, to vegetable and ephemeral elements – the reference to the surrounding space, to change and transience is inextricably linked to the concept of material.

This opens up the broad field of meanings that are gained in the artistic transformation of the material and which in turn interweave it with existential, everyday and social experiences and concepts. material messenger is curated by Elisabeth Sonneck and Juliane Rogge. The exhibition includes works from the Schroth Collection and from invited artists:

Julieta Aranda | Aram Bartholl | Burghard | Angela de la Cruz | Spencer Finch | Abie Franklin & Daniel Hölzl | Jason Gringler | Carla Guagliardi | Vanessa Henn | Iepe | Zhanna Kadyrova | Katja Kottmann | Linda Lach | Jamie North | Anton Quiring | Ulrich Rückriem | Maarit Salolainen | Karin Sander | Nora Schattauer | David Semper | Berndnaut Smilde | Elisabeth Sonneck | Ignacio Uriarte | Christoph Weber | Beat Zoderer

From Cosmos to Commons: Between Stars and Signals

21. June – 17. August 2025
Gruppenausstellung, Kunsthaus Hamburg, Hamburg

Participating artists: Aram Bartholl, Zach Blas, Nolan Oswald Dennis, Charles & Ray Eames, Sasha Litvintseva & Beny Wagner, Timo Nasseri, Norbert Pape & Simon Speiser, Trevor Paglen, Katie Paterson, Marie Pietsch, Agnieszka Polska, Jana Schumacher, Hoda Tawakol.

How do we navigate a world in which our actions have a planetary impact? In our post-global era, we cannot see ourselves merely as inhabitants of the Earth. Essentially, we are geological actors whose economic, ecological and political decisions leave profound marks on the globe. From this perspective, the Earth can be viewed as a dynamic system within a much larger cosmic structure.

The group exhibition Between Stars and Signals at the Kunsthaus Hamburg focuses on the bigger picture and spans an arc from humanity’s early understanding of the world and its orientation on the stars all the way to the planetary paradigm and modern technologies such as GPS. The participating artists have engaged in the topic of physical movement through space and time along with its philosophical and social implication. The works on view, spanning video, wall and spatial installations, reflect complex relationships between humans, nature and the cosmos – and make us think. For the question remains whether the digital transformation will lead to a deeper cosmic consciousness or whether it will distance us even further from our immediate experience of the world.

From the Cosmos to the Commons marks the beginning of the five-year programme conceived by City Curator Joanna Warsza. In 2025, it includes exhibitions at the Planetarium Hamburg, Stadtpark, the Kunsthaus Hamburg and a symposium at the Warburg Haus. Since 2024, the project City Curator Hamburg has been hosted by Kunsthaus Hamburg.

Grand Snail Tour

26. September 2024 – 29. August 2025
Gruppenausstellung, Urbane Künste Ruhr, Xanten Ruhrgebiet

What is the Ruhr area? An exciting metropolitan region centred around the major cities of Dortmund, Essen and Duisburg? Or a collection of scattered towns and villages from Alpen to Xanten? Or both? Does it consist of tranquil river landscapes along the Ruhr, Emscher and Lippe or is it hopelessly damaged by the scars of heavy industry? Ruhrpott, example of transformation, poverty zone – how can art open up, change and enrich this diverse region?

Urbane Künste Ruhr wants to find out and is launching the Grand Snail Tour in autumn, an artistic-performative journey through all 53 cities in the Ruhr region. Because this is an ambitious endeavour and Urbane Künste Ruhr has set itself the goal of getting to know local players, forming bonds and establishing sustainable networks, this is a three-year project.

Kick-off Grand Snail Tour in Xanten
Urbane Künste Ruhr is launching the Grand Snail Tour in autumn, an artistic-performative journey through all 53 cities in the Ruhr area. The kick-off event will take place on 26.9. in Xanten.

MINIMALE REVOLTE Festival

23. July 2025
Gruppenausstellung, Public space, Charlottenburg, Berlin

The festival brings artistic short films into public space – presented in a mobile, seemingly
improvised exhibition object: a transport cart with pneumatic tires, stacked with various boxes,
crates and bags, all secured with colorful tension straps. Through peepholes in these containers,
passersby can watch the films on hidden tablets or smartphones.
The route leads through five locations in the district (Goslaer Platz, Mierendorffplatz,
Österreichpark, Schustehruspark, Lietzenseepark). At each stop, the “mini-museum” stays for
about one hour. The project is accompanied throughout the day by the two artists and curators
Marian Luft and Moritz Frei, who will be present to assist and engage with the audience.

Echokammer

20. – 22. June 2025
Gruppenausstellung, Fasskeller, Berlin

mit: Aram Bartholl, Hannah Hallermann, Verena Issel, Anne Mundo, Finja Sander, Moritz Stumm / Stefan Neuberger,Philip Topolovac, Viron Erol Vert
kuratiert von Dirk Teschner

Der Ursprung des Begriffs Echokammer findet sich in der analogen Tontechnik als architektonischer Bestandteil eines Tonstudios und dient der Erzeugung oder Verstärkung des Halls. Ein starker Hall (Nachhall) entsteht mit acht oder mehr Sekunden in Kirchen. Echo ist ein verstärkter Nachhall mit darüber hinausgehenden Zeiten.

Außerhalb von Ton und Hall verweist der Begriff Echokammer auf einen Raum, in dem Aussagen verstärkt und Störgeräusche, etwa anders lautende Meinungen, geschluckt werden. Der Großteil der Menschen neigt dazu, sich mit Gleichgesinnten zu umgeben, um sich gegenseitig in einem geschlossenen Raum in der eigenen Position zu verstärken. In einer Echokammer rezipieren Mediennutzer hauptsächlich Informationen, die ihre eigenen Ansichten unterstützen. Mit Argumenten, die ihre Meinung in Frage stellen, setzen sie sich dagegen kaum auseinander. Dadurch entstehen geschlossene Netzwerke. Die Folge ist eine Verschärfung der politischen Debatte, ohne Hall ins fremde Tal. Die Suche nach einem gemeinsamen Klang kann aber nur außerhalb der engen Kammern gelingen.

Loops Series

22. May 2025
Talk, New Practice in Art and Technology, MA Design & Computation TU Berlin, Berlin

Loops is the public event series of New Practice in cooperation with the Berlin University Alliance exploring current questions facing our society at the intersection of art, science and technology in a unique discursive format. Afterwards, the Bar provides a space for exchange between guests, researchers, students and the public.

This session welcomes Aram Bartholl, a seminal voice in contemporary media art whose work interrogates the blurred threshold between digital systems and physical life. Merging conceptual art, hacker culture, and urban intervention, Bartholl’s installations and performances expose the hidden infrastructures of the internet while playfully reanimating digital symbols into everyday public space.

‚DeafenYourPhone‘ – How to make sure your phone is not listening on you

August 23, 2016

The ‚DeafenYourPhone‘ tube is a mobile, low-cost, DIY sound dampening solition to prevent supposedly hacked phones from eavesdropping on its owner.

deaf-chamber-for-smart-phones-01
The Matryoshka tube in a tube concept works well to isolate a phone sound proof from its environment.

To avoid impact sound transmission the tubes are isolated with foam. Add another tube if you want to increase the sound proofing quality.

Dimensions: 12 x 12 x 30 cm ; weight: 1 kg ; material cost: 24,- €
The problem
Once targeted a standard mobile phone can be hacked by an attacker and easily be modified to record sound at any time. This might sound like a farfetched spy story to you but in the year 3 after Snowden politicians, lawyers, NGOs or journalists have to deal very much with these kind of questions. Recently Edward Snowden & Bennie Huan presented the project „Introspection Engine“, a hardware modification for iPhones that monitors and signals radio traffic on a hardware level to make sure the phone is ‚really off‘. Different voices in the hacker community pointed out that this device cannot prevent phones from listen to a conversation and to relay the data ‚later‘ to the ‚attacker‘. It is generally advised for i.e. journalists who are meeting a ’source‘ to leave their phones ‚at home‘ or in a sound dampening closet like a fridge nearby. However, depending on the local situation this is not necessarily a practical solution. You might need the phone to plan the meeting and maybe the place where you meet has no fridge or similar appliances accessible.
How does it work?
Like a russian Matryoshka doll the phone is locked into a foam isolated plastic tube with screw cover, which again is placed in an isolated plastic tube. After a series of tests with different containers it showed that a round tube of hard plastic provides good properties to block sound. It is very important to disrupt direct contact of the phone case and plastic tubes to avoid impact sound transmission. The double layer tube in a tube approach can be improved with a 3rd or more layers of plastic tubes. Surprisingly it is quite difficult to prevent a phone microphone from ‚hearing‘ something. Try it yourself! I did tests with pouches, boxes, kitchen containers, glass containers, pelican cases and so on. Often there the recorded sound is already very low but always good enough to listen to a conversation once you pull up the volume in post-production audio software. Heavy high density material would work best to block sound waves but to walk around with a concrete block seems not very practical. However if you find out other better solutions please share your ideas!
Tutorial:

  1. Get different size plastic drain tubes and covers with rubber seals from your local DIY store. Screw covers are advised but sometimes harder to get. In german the grey tubes are called ‚HT-Rohr
  2. Buy some foam. I used just 10 mm standard foam but there is also special foam for sound canceling available i.e. in the auto mobile market available. Total cost of tubes and foam ca 24,- €
  3. Place the phone in the isolated tube and close the cover tight. Make sure the phone cover is not touching the tube directly. Place the small tube in the big tube and also close this one tight.
    ( The small tube I got only has diameter of only 7,5 cm. Small size smart phones still fit in here. Any new iPhone or Samsung will need a bigger tube. )

Disclaimer!
Make sure to test your setup! Put your phone to record audio and lock it in the tubes. Try different sound sources in a variety of distances to the DeafenYourPhone tube and check the results in audio software on your computer. In a normal medium sound environment, with a distance of 1-2 meters and normal voice speaking level I wasn’t able to extract any usable audio from the recordings. Only rely on this proposal for a sound proofing capsule if you have tested and proofed its function properly. Tips and recommendations from audio/eavesdropping experts are welcome! 😉
History
I presented this sound proof tube concept along with the killyourphone.com pouches workshop end of 2013 at the #30C3 conference, the annual congress of the CCC (Chaos Computer Club) but haven’t documented it properly since then. This blog post is dedicated to Linus Neumann and Tim Pritlove from Logbuch Netzpolitik.org. ;))
Audio test!!
This is an audio test with the above shown setup. „Logbuch Netzpolitik“ #190 is running at a decent volume (normal voice level). The tubes are closed and then placed ca. 1m away from the speaker. If you are able to extract the conversation of Tim and Linus while the phone (iPhone 5) is in the tube please let me know!

‚Nice to see you‘

Mai 31, 2009


It’s kind of natural nowadays that a meeting point is monitored by a surveillance cam. But in this particular case (at airport Tegel, Berlin, DE) it is interesting that the logo of the meeting point looks exactly like the cam itself.
