Der Fokus liegt auf der musikalischen Erforschung roher elektronischer Klänge ohne den Einsatz von Echo, Hall oder Loopern. Auch wenn es rhythmische Momente geben mag, stehen diese nicht im Mittelpunkt, ebenso wenig wie Harmonie und Melodie – vielmehr sind technische/mathematische Strukturen die Ausgangspunkte. Die ästhetische Anziehungskraft entsteht durch die Akzeptanz des Klangmoments als kognitive Erfahrung und die gemeinsame Wahrnehmung eines Spannungsbogens durch Publikum und Performer*in.Improvised electronic music on a hybrid setup consisting of a small modular system and digital components programmed in Pure Data. The focus is on the musical exploration of raw electronic sounds without the use of echoes, reverb, or loopers. Even though there may be rhythmic moments, these are not the focus, nor are harmony and melody—rather, technical/mathematical structures are the starting points. The aesthetic appeal arises from the acceptance of the sound moment as a cognitive experience and the shared perception of a tension arc by the audience and performer. #### Artist Bio: i am an electronic/experimental musician, composer, improviser, programmer based in leipzig/germany. after more than 3 decades as a professional musician and instrumental teacher in various styles and on various traditional instruments, i have become a little bored and saturated with it. in addition, i have felt the desire to devote my life to other tasks such as left wing political, activist work and exploring the social space. therefore i have decided to stop making traditional music and to focus musically on improvisation and electronic sound generation. this allows me to combine some strong interests - for example, exploring sounds, computer programming, electronic tinkering - and use them for my artistic work. i play live with a small modular system as well as with self-developed digital, computer-based instruments and controllers. in addition to ensemble improvisation, i am increasingly interested in solo performances. through my long time as a wind instrumentalist i have become accustomed to always using my breath for articulation and dynamic control. that's why i usually use a breath controller for my electronic performances. in this concert i expect to use an eurorack-modular in combination with pure data & supercollider https://events.ccc.de/congress/2025/hub/https://usercontent.events.ccc.de/congress/2025/hub/usercontent/e/ba338e686236/1120-700-max.jpgMartyhttps://events.ccc.de/congress/2025/hub/event/detail/noisy-improvised-concert-on-analogdigital-modular-false2025-12-27T14:30:00+01:0014:3002:00Call for Art: Workshopspace 139c3-pixelprinting-with-bricksotherWorkshop with pixelprint * DAY 1: 14:30 - 16:30 * DAY 2: 14:00 - 16:00 * DAY 3: 14:00 - 16:00We print with building block tiles, also known as Lego Dots™, on paper.

Repariere keine Autos, sondern mach lieber etwas im Leben, was du wirklich willst.“ Elias fragt sich: Muss man sich zwischen Selbstverwirklichung und selbstlosem Handeln entscheiden? Wovon hängt die Verantwortung gegenüber Einzelpersonen oder der Gesellschaft insgesamt ab?**Artist: Christoph Fleischer** **Genre: Documentary, 92 min** *DE with EN subtitles, 2024* Theatre engineer Elias builds a fully functional steampunk submarine together with his friends. While Nico rescues people from the waves of the Mediterranean, the 70-year-old artist Jim advises: ”Don‘t do it. Don’t fix cars, but rather do something in life that you really want to”. Elias asks himself: Is there a decision to be made between self-realization and selfless-action? Upon what does responsibility towards individuals or larger society depend? ABOUT WATER AND DREAMS is a philosophical journey that questions the meaningfulness of our actions and dares to dream publicly in our dreamless society.

Der Fluss und die Bewegung des Wassers steuern und lösen die Stimme aus und schaffen so ein einzigartiges Zusammenspiel zwischen den beiden Elementen. Es fängt die Stimme mitten in ihrem Trainingsprozess ein – wie sie sich verändert, stolpert und neu interpretiert. Während sich das Wasser bewegt, formt und unterbricht es den Klang und verwandelt die Bewegung der Flüssigkeit in eine stimmliche Geste. Das Ergebnis ist weder rein menschlich noch rein künstlich, sondern etwas dazwischen – lebendig, instabil und sich ständig verändernd. „Water to Voice“ wird zu einem Dialog zwischen Natur und Technologie, einer fragilen Choreografie, in der die Stimme in Echtzeit lernt, ins Stocken gerät und sich weiterentwickelt.»Water to Voice« is an evolving piece born from the process of cloning Lisa’s voice. The flow and movement of water control and trigger the voice, creating a unique interplay between the two elements. It captures the voice in the midst of its training—shifting, stumbling, reinterpreting itself. As the water moves, it shapes and disrupts the sound, transforming liquid motion into vocal gesture. What emerges is neither purely human nor purely artificial, but something in between—alive, unstable, and constantly transforming. »Water to Voice« becomes a dialogue between nature and technology, a fragile choreography in which the voice learns, falters, and evolves in real time. Artist Bio: The duo Lisa L. Zwinzscher & Nina Bendix Igleses (Leipzig/Weimar) explores the boundaries of listening and voice in the digital realm. Emerging from Lisa L. Zwinzscher’s solo project Pony Pracht, which blends music with interactive, game-inspired visuals, her work expands to questions of identity and authenticity in the age of AI. As a singer, she has cloned her own voice, transforming it into a human-artificial live instrument.  Fascinated by the tactile, sonic and metaphorical qualities of water, Nina Bendix Igleses approaches listening as a multisensory practice of relating to the world, investigating interconnection within and between self and environment. Together, they engage with questions of identity, resonance, and transformation, creating sonic environments that explore what it means to be human.

TAG 4: 11:30 - 13:00In this workshop, we will engage with digital publishing methods that operate independently of big tech platforms and products. We will build our own RSS files for personal websites, blogs and discuss pirate publishing forms, both online and offline. We will present the idea of the PPDP-PRINTER, a DIY device currently under development that combines web2print scripts with a simple server and local online publishing/broadcasting capabilities. The printer converts files, prints via its dot-matrix printer, creates RSS feeds, and serves them online. Our aim with the PPDP-PRINTER is to create an all-in-one material manifestation of our resource collection Post-Platform Digital Publishing Toolkit Please bring your laptop.

Each participant builds her own board to drive two motors that will then tap in polyrhythms. The electronic circuits in this workshop derive from minimal and low-cost bio-inspired robots. Oscillators are used to drive motors that produce sound, but they can also be connected to synthesizers. Each circuit board is designed to be wired up with the boards from the other participants in order to explore together the magic of emergent polyrhythm by wiring their individual circuits to form a huge network. Big fun and deep dive into analog circuits and their emergent properties.

Auch wenn es rhythmische Momente geben mag, stehen diese nicht im Mittelpunkt, ebenso wenig wie Harmonie und Melodie – vielmehr sind technische/mathematische Strukturen die Ausgangspunkte. Die ästhetische Anziehungskraft entsteht durch die Akzeptanz des Klangmoments als kognitive Erfahrung und die gemeinsame Wahrnehmung eines Spannungsbogens durch Publikum und Performer*in.Improvised electronic music on a hybrid setup consisting of a small modular system and digital components programmed in Pure Data. The focus is on the musical exploration of raw electronic sounds without the use of echoes, reverb, or loopers. Even though there may be rhythmic moments, these are not the focus, nor are harmony and melody—rather, technical/mathematical structures are the starting points. The aesthetic appeal arises from the acceptance of the sound moment as a cognitive experience and the shared perception of a tension arc by the audience and performer. #### Artist Bio: i am an electronic/experimental musician, composer, improviser, programmer based in leipzig/germany. after more than 3 decades as a professional musician and instrumental teacher in various styles and on various traditional instruments, i have become a little bored and saturated with it. in addition, i have felt the desire to devote my life to other tasks such as left wing political, activist work and exploring the social space. therefore i have decided to stop making traditional music and to focus musically on improvisation and electronic sound generation. this allows me to combine some strong interests - for example, exploring sounds, computer programming, electronic tinkering - and use them for my artistic work. i play live with a small modular system as well as with self-developed digital, computer-based instruments and controllers. in addition to ensemble improvisation, i am increasingly interested in solo performances. through my long time as a wind instrumentalist i have become accustomed to always using my breath for articulation and dynamic control. that's why i usually use a breath controller for my electronic performances. in this concert i expect to use an eurorack-modular in combination with pure data & supercollider https://events.ccc.de/congress/2025/hub/https://usercontent.events.ccc.de/congress/2025/hub/usercontent/e/727d9d3de403/1120-700-max.jpgMartyhttps://events.ccc.de/congress/2025/hub/event/detail/xl-noisy-improvised-concert-on-analogdigital-modulfalse2025-12-29T22:30:00+01:0022:3001:30Art & Play: Bus Stage39c3-traumtaucherde, enotherDer Theatertechniker Elias baut zusammen mit seinen Freunden ein voll funktionsfähiges Steampunk-U-Boot.

Repariere keine Autos, sondern mach lieber etwas im Leben, was du wirklich willst.“ Elias fragt sich: Muss man sich zwischen Selbstverwirklichung und selbstlosem Handeln entscheiden? Wovon hängt die Verantwortung gegenüber Einzelpersonen oder der Gesellschaft insgesamt ab?**Artist: Christoph Fleischer** **Genre: Documentary, 92 min** *DE with EN subtitles, 2024* Theatre engineer Elias builds a fully functional steampunk submarine together with his friends. While Nico rescues people from the waves of the Mediterranean, the 70-year-old artist Jim advises: ”Don‘t do it. Don’t fix cars, but rather do something in life that you really want to”. Elias asks himself: Is there a decision to be made between self-realization and selfless-action? Upon what does responsibility towards individuals or larger society depend? ABOUT WATER AND DREAMS is a philosophical journey that questions the meaningfulness of our actions and dares to dream publicly in our dreamless society.

From hommages to our own ideas, we created several works – sixty years after the first exhibitions. You can find some of these works on the walls of the CCH.

Have a look at the gallery to see some examples. We print using a press from the Open Press Project. The print size is limited to 7×7 cm due to the press we are using. It is a “jump-in” workshop with no registration required – when one person leaves, the next can join in.

Education is no longer about learning—it's financial control dressed up as opportunity. Students graduate with crushing loans. Professors work precarious jobs. Administration consumes budgets that should fund actual learning. Knowledge is sold, credentialed, gatekept. But what if we could reimagine this completely? Not reform universities—redesign them from scratch. In this workshop, we're asking CCC participants to collectively design the university of our dreams. Not the university we think is "realistic" or "achievable within current constraints." The university we actually want. Here are the questions: Should it be distributed or centralized? Fully virtual or partially offline? How do we use open-source technologies to eliminate bullshit jobs, administration, and bureaucracy? How do we make education free, accessible, and democratic? Can a university exist without exams, without filtering students, accepting everyone who wants to learn? How do we build around open libraries—like David Graeber's music and book collections at davidgraeber.org—that anyone can modify and contribute to? How does this become not an institution, not a nation-state project, but a community of experimenters distributed globally? Ultimately, this is about technologies—survival technologies. Social technologies. Poetic technologies. https://events.ccc.de/congress/2025/hub/https://usercontent.events.ccc.de/congress/2025/hub/usercontent/e/d32242c10f60/Poetic_Technologies_and_an_open-source_university.jpeghttps://events.ccc.de/congress/2025/hub/event/detail/poetic-technologies-and-an-open-source-universityfalse2025-12-29T20:30:00+01:0020:3001:30Call for Art: Workshopspace 139c3-how-to-break-your-face-keeping-up-with-the-ar_4dyzenotherWorkshop with Anna Maria & Michelle Tylicki * DAY 1: 18:00 - 19:30 * DAY 2: 17:30 - 19:00 * DAY 3: 20:30 - 22:00Facial recognition systems are rapidly advancing - fusing infrared, facial geometry, gait, and metadata into oppressive infrastructures of racist policing and surveillance capitalism. At the same time, artists, activists and everyday citizens are developing creative ways to interfere, confuse, and disappear from automated identification. #### Workshop 1: Break Your Face Hands-on demonstration of Dazzle anti-surveillance makeup techniques. Live-testing our work to understand machine vision -and how to break it. #### Workshop 2 + 3: Zine-making Starting with a discussion of creative anti-surveillance tactics, we then combine the workshop participants' knowledge and experience to co-creating a zine. Info: We will be using easily available live face filters on smart phones (instagram/snapchat/tiktok). Participants can use their own phones. The data is not uploaded or saved anywhere.

Debra Guckenheimer has taken discarded books and created collages to feature as a backdrop to an affirmation. The affirmation is a rejection of an ableist message she received with a disability justice message on the back. She has distributed over 100 postcards around the world to friends and strangers, who keep the postcard up to recite the affirmation as needed. Audience and artist together create change as they practice letting go of harm. This is Debra's first exhibit in Germany, the home of her grandparents until they fled in 1933, as Debra practices healing some of the trauma her ancestors experienced. This workshop is dedicated to the late disability justice Alice Wong and the ancestors of Debra who were murdered by Nazis. Attendees will receive a disability justice postcard (limited quantity available) to practice healing and resistance. https://events.ccc.de/congress/2025/hub/event/detail/disability-justice-art-as-praxisfalse2025-12-29T16:00:00+01:0016:0003:00Call for Art: Workshopspace 239c3-electronic-oscillators-for-organic-patterns-and-pootherWorkshop with Christian Faubel * DAY 2: 16:30 - 19:30 * DAY 3: 16:00 - 19:00 Performance DAY 4: art&play [tba]This is an advanced soldering workshop for creating motorcontrollers that bring motors to tap rhythmically with each other. Each participant builds her own board to drive two motors that will then tap in polyrhythms. The electronic circuits in this workshop derive from minimal and low-cost bio-inspired robots. Oscillators are used to drive motors that produce sound, but they can also be connected to synthesizers. Each circuit board is designed to be wired up with the boards from the other participants in order to explore together the magic of emergent polyrhythm by wiring their individual circuits to form a huge network. Big fun and deep dive into analog circuits and their emergent properties.

These exhibitions of  Georg Nees, A. Michael Noll with Béla Julesz and Frieder Nake with Georg Nees took place in Stuttgart and New York. We looked into different techniques of algorithmic drawing. From hommages to our own ideas, we created several works – sixty years after the first exhibitions. You can find some of these works on the walls of the CCH. Additionally, we want to give several interactive workshops. Here, you can experiment on your own drawings and take them home.

We will build our own RSS files for personal websites, blogs and discuss pirate publishing forms, both online and offline. We will present the idea of the PPDP-PRINTER, a DIY device currently under development that combines web2print scripts with a simple server and local online publishing/broadcasting capabilities. The printer converts files, prints via its dot-matrix printer, creates RSS feeds, and serves them online.

Strengthening non-tech communities is essential for our collective well-being. What is the minimum level of tech education that everyone engaged in class struggle should acquire? Do we have the tools to protect non-tech people in our environment beyond the hackerspaces communities? How to build horizontal safe-spaces, secure infrastructures to educate others and which tools and techniques are the most effective for education? Let's have a discussion and create ready to use solutions.
