Robert Rauchenberg: Mud Muse

Robert Rauschenberg, Mud Muse, 1968–71; Moderna Museet, Stockholm, gift of the New York Collection

Mud Muse,  a kinetic artwork created between 1968 and 1971 by American artist Robert Rauschenberg,  in collaboration with engineers from Teledyne( through the Art & Technology program at the Los Angeles County Museum of Art), is a large aluminum-and-glass vat that contains an enormous amount of mud, weighing thousands of pounds. Although considered mud by standard terminology, its more appropriate content appellation is bentonite, an absorbent, swelling clay composed of montmorillonite, from weathered volcanic ash.

The mixture is stirred to a distinctive viscosity in the vat, over the course of several hours or days. The primary allure of the art piece is the bubbles produced with the aid of pulsing air valves that are located beneath the surface of the mud. This is connected to an adjacent prerecorded soundtrack that emits sound from a 1960s reel-to-reel. The sound pushes air through the valves, resulting in a physical manifestation of sound emission.  Rauschenberg imagined different audio stimuli, including traffic noises, police sirens, and, most ambitiously, real-time sounds made by visitors that would be picked up by a hanging microphone. In the end, he decided that Mud Muse, when officially displayed for the public, would “play itself,” essentially a recursive loop of the audio made by the bubbles. 

American artist Robert Rauschenberg

Rauschenberg (1925-2008), born in Port Arthur, TX, is considered a pioneer in the art scene due to his early adaptations of technology in his work, such as radios, electric lights, and clocks, as well as his more renowned printmaking works. His endeavors into kinetic art began in 1960, after meeting Swiss artist Jean Tinguely. Together, they created several kinetic works alongside engineer Billy Klüver, such as Oracle (1962–65), a sonic sculptural environment, and Soundings (1968), an immersive, voice-activated sound and light installation. This era, which was marked by technological innovation and space exploration, ultimately played a pivotal role in Rauschenberg’s creation of Mud Muse.

In modern days,  Mud Muse acts as a tradition passed down through the years. The current installer, Gunnar Marklund, notes that “The audio equipment and its cabinet are quite old and require maintenance and repair on occasion. And there are sixty-four valves in the bottom of the pool, and they do get clogged; I have to check them every time and clean them as needed.”  Occasionally, during installation, he experiments with different music to activate the bubbling (in New York recently, ABBA). Overall, the knowledge he has gained over 19 years, he passes on to future generations.

In recapitulation, Mud Muse acts not only as a visual experience, but one that activates hearing, smell, and touch, allowing the public to have a holistic and interactive participation with the piece.  It collides two opposing worlds of ancient material and modern technology, creating a piece of art that has withstood the tests of time and continues to bewilder audiences.

Karim+Elias: From This Earth Installation

Location:  Diriyah, Saudi Arabia
Year:  2024
Project Type:  Temporary installation / pavilion
Area:  220 m²
Architects:  Karim+Elias
Lead Architects:  Karim Tamerji, Elias El Hage
Photography:  Elias El Hage
Event Design and Coordination:  Design Lab Experience

Project Overview
From This Earth Installation is a temporary installation by Karim+Elias in Diriyah, Saudi Arabia. Completed in 2024, the 220 m² project was presented as part of Layali Diriyah and consists of a series of porous earthen screens assembled from more than 1,400 hand-sculpted spheres. Rather than treating earth as a heavy and continuous wall, the installation reimagines it as a modular, open-air spatial filter. In this sense, the project is significant not only as an installation, but also as a contemporary experiment in earthen material practice.

Site and Cultural Context
The project is deeply tied to its location. Diriyah is described by its official destination platform as the “City of Earth,” and it is presented as the birthplace of Saudi Arabia. Within this context, From This Earth operates as more than a temporary pavilion: it becomes a material response to a place historically associated with earthen building traditions. The architects state that the work celebrates Diriyah’s craft of building with earth, so the project should be understood as a contemporary reinterpretation of local architectural memory rather than as an abstract sculptural object placed in a neutral site.

Material and Construction Logic
Karim+Elias describe their broader practice as a contemporary exploration of “sculpting with sand,” using locally sourced earth, clay, and water in custom-made moulds. In From This Earth, this material approach appears through a system of over 1,400 hand-sculpted modular spheres made from local material and stacked into earthen screens. This construction logic is important because it shifts earth away from its more familiar role as a monolithic mass or thick wall. Here, earth becomes a repeated unit, a surface condition, and a space-making device. The project therefore demonstrates how traditional earth-based craft can be translated into a contemporary modular language.

Spatial Experience
The installation’s spatial effect comes from porosity. The stacked spherical modules create filtered views, partial enclosure, and changing patterns of light and shadow. Designlab Experience describes the screens as evoking the traditional mashrabiya and recalling Diriyah’s vernacular triangular wind openings and rooftop silhouettes. Because of this, the project does not simply represent earthen architecture visually; it performs some of its environmental and perceptual qualities. Air, light, depth, and visibility are mediated through the earthen surface, allowing visitors to experience earth not only as a material, but also as an atmospheric interface.

Significance to Contemporary Earthen Practice
This project is relevant to contemporary earthen architecture because it expands the definition of what an earthen work can be. It does not reproduce a traditional mud structure directly, nor does it use earth only for symbolic effect. Instead, it repositions earthen craft within a temporary cultural installation and demonstrates that earth can function as a contemporary design medium. From This Earth shows that earthen practice today can move across architecture, installation, art, and public event design while still remaining grounded in local material and cultural context.

Zabur in Yemen

Aljazeera

The Architecture found in Yemen is among the most sophisticated and enduring traditions in human history – a monument to the reaches that people could build to even without modern, post-industrial materials and methods. These relics, often older than 500 years old, are more at risk than ever, due to socio-political issues in yemen.

Central to this architectural tradition is the “zabur” technique, which is among a collection of practices essential to earthen architecture in Yemen, from the coursed-clay methods in the highlands to the iconic “gingerbread” fired-brick patterns found in the capital, Sana’a.

The master builders “ustads” utilize several distinct systems based on the required outcome – each varying the preparation of the earth, the firing or not-firing of that earth, and the methods of application. This allows zabur to adapt to the various features of the yemeni landscape – optimizing from the humid coastal plains to the volcanic plateaus.

 

NBC NEWS

In technical literature, “zabur” is defined as a direct-forming technique – utilizing wet, straw-reinforced clay soil to build walls without the use of formwork or molds. This is reminiscent of the European technique of “cob.” This definition of the term, however, is limited – and many linguists and experts of old Sana’a argue that it’s also inextricably linked to the intricate patterns of the fired-mud bricks that comprise much of the city’s facades. This intertwines the later, post-Islamic styles of decorative brick-and-gypsum towers with the ancient past’s monolithic clay walls – what I’ll call “pure zabur.”

ArabAmerica

In the northern regions, zabur remains as a pure coursed-clay tradition. The material is prepared in pits and formed into balls, which are then thrown to the master mason standing on top of the wall, who settles the material into place. In Sana’a, the zabur is the fired mud-bricks that are adorned with ornamentation drawn of white gypsum.

Tower House

These techniques allowed Yemeni to build stronger, and then eventually higher – leading to the creation of tower houses. These traditional tower houses in the old cities were set on stone foundations of basalt, on top of which carefully fitted, locally quarried tuffa and limestone up to 10 meters tall is laid. Above that, the zabur bricks are laid – and then on top of that an aged lime plaster called qadad is applied as an exterior waterproofing layer (atleast on the rooftops).

MIT Libraries

Yemeni Architecture reflects a “profound interaction between humans and their environment“(IJSDP), standing as a creative embodiment of beauty, simplicity, and the extents of human ingenuity of the past. Rapid urban development in recent years, however, has created disharmony and a detachment from societal traditions – something that looking at and preserving techniques from the past may help with reconciling.

Robotic Ramming

Digital Futures 2025 Workshop
CAUP, Tongji University
Institute of Structural Design, TU Braunschweig

https://www.tu-braunschweig.de/ite/research#robot-aided-fabrication-of-rammed-earth-elements

June 2025

Robotic Ramming – Digital Futures 2025 was held in June 2025 at CAUP, Tongji University, and led by the Institute of Structural Design at TU Braunschweig. The workshop was directed by Dr. Samim Mehdizadeh, Joschua Gosslar, and Noor Khader under the academic leadership of Prof. Dr. Norman Hack and Prof. Dr.-Ing. Harald Kloft.

The workshop investigated the integration of robotic fabrication with rammed earth construction. Moving beyond traditional in-situ methods that rely on rigid formwork and horizontal layering, the project employed a robotic arm equipped with a pneumatic ramming end-effector. This system enabled digitally controlled compaction and expanded the geometric possibilities of earthen construction.

Participants developed a complete design-to-fabrication workflow. Using Rhino and Grasshopper, they generated toolpaths through boundary definition, sectional slicing, voxel allocation, infill pattern development, and sequential ramming strategies. Digital modeling was directly linked to material performance and robotic execution.

The workshop culminated in a large-scale demonstrator composed of three rammed earth components, each approximately the size of a Euro pallet and varying in height. The installation demonstrated scalability, structural articulation, and the potential of robotic ramming as a sustainable construction method.

Cob in the UK

Cob in the UK and Ireland – England and Wales 

Historical Context-13th Century-15th Century

In the 13th Century, Cob first established as a basic technique in the UK began to evolve in practice for many years. As the development of homes changed over time cob developing into the framework of a more industrialized society in the 15th Century. This became a normal form of buildings utilizing various material mixes for more solid mass use. Established mainly in certain regions like Devon, Cornwall, Somerset and parts of East England, as well as Wales. Historically, various forms of architecture were also established in the adjacent country of Ireland where sod houses and thatch cottages which were more common practices. Along with the UK cob houses materials were used similarly in tangent and later developed in the same fashion. Location in context worked well with the mild maritime climate, clay rich soil and easily accessible materials.

Building Techniques and Materials

Material

Historically, cob was more common in England and Wales the sandy clay material of the natural environment was a more viable option considering that stone and wood were less accessible. This allowed various mixtures to form ranging from different percentages of clay, straw and water ration. In order to create a thick more workable mixture.

The technique primarily uses a mixture of clay, sand, stone straw and water combined with a lime mortar for durability. The form was then applied molded by hand allow sculptural forms to construct characterized architectural forms.

Cornish lime mortar is an essential material used for maintaining cob structures as it allows a longevity and stability over time. The lime mortar allows for flexibility of the structure while also preventing cracking and breakage. Lime can also be fire proofing, water resistant and durable.

There are certain forms of cob that use a chalk heavy concentrate and are know as chalk cob or wychert. This gives a distinctive natural blend of materials for the walls, consisting of most of the housing in the UK during the vernacular period.

Highly Skilled Labor

Hand shaped and compressed, highly skilled labor is required for the creation of cob walls and or cob bricks. The mixture is laid onto a stone foundation and does not require formwork or ramming. Construction would consist of building on top of another layer after drying and trimming for the next batch to be laid.

Heritage Cob mixtures

Generally about 24 inches thick, for walls and or brick forms creating spaces for windows inset, the overall thickness of the material allows a natural insulation during the day.

Longevity, Maintenance and Sustainability

Longevity

Still being used in practice today the longevity of the cob wall, offers a deeper understanding of the practice for breathability, prolong building life as well as establishing a lasting sustainable practice.

Considering that the construction of these buildings were created in the 13th to 19th century enough of these buildings mixtures allowed occupation of these houses to this day.

Maintenance 

Cob wall repairs are common to not only keep up with the historic longevity but to address minor issues that arise before escalation and cracking. Some methods of maintenance include patching up areas affected by moisture as well as adding new coats of lime mortar for more stability and durability. This also helps keep out any newer moisture to prevent further decay over time. Though maintenance may be subjected to certain craftspeople it still is a viable form of building practice for eco based materials.

Sustainability

Emphasizing a breathable material and establishing the lime coat to prevent moisture, cob allows a breathable structure that  can regulate the internal climate and heat within  fluctuating  weather. The thermal properties as well as the breathability allows faster moving heat as well as more stability of the climate in the interior.

Along with being a thermal based building the durability against various weather events including windy, rainy and moisture rich conditions make the weather resistance a factor in preventing breakage of materials and mold content.

Considering that the materials are natural it works in harmony well with the built environment. Using these materials have minimal impact on the ecosystem as a whole and can also be considered a renewable resource.  It can cut back on carbon emissions for building and can also be a viable option for housing in the future.

Future of Cob in the UK

There are some craftspeople that are supporting the movement to look more into cob as a building practice for present day architecture. Bringing a contemporary use of this material there are various forms of cob that has become a more viable option for building
