<nettime> Relational Architecture |
[relational info: this text is based on a lecture i attended in Tenerife, a Canarian island where James Bond lives between his movies. it was early before christmas, an extraordinary setting around good old k-words like virtual persona, digital humans, cyberidenties, when suddenly electricity went down, so Sandy Stone took the chance and gave a formidable uncanny no-tech performance inside this dark medieval fortress near to the sea. It is recommended to follow Raphael's links to get a picture of the described works. i found the presented works interesting as an experimental aproach to recontextualise and shift what was once called interactive media art - the event was organized by Daniel Canogar, http://www.in-art.com --- apologies for the recent severe hickups: we are currently renovating nettime to make rotating group moderation possible /p] RELATIONAL ARCHITECTURE GENERAL CONCEPT: ======================= [by Raphael Lozano-Hemmer] (Definition:) Relational architecture can be defined as the technological actualisation of buildings and public spaces with alien memory. Relational architecture disorganizes the master narratives of a building by adding and subtracting audiovisual elements to affect it, effect it and re-contextualize it. Relational buildings have audience-activated hyperlinks to predetermined spatiotemporal settings that may include other buildings, other political or aesthetic contexts, other histories, or other physics. (Differences between virtual and relational architecture:) Virtual architecture could be differentiated from relational architecture in that the former is based on simulation while the latter is based on dissimulation. Virtual buildings are data constructs that strive for realism, asking the participant to "suspend disbelief" and "play along" with the environment; relational buildings, on the other hand, are real buildings pretending to be something other than themselves, masquerading as that which they might become, asking participants to "suspend faith" and probe, interact and experiment with the false construct. Virtual architecture tends to miniaturize buildings to the participant's scale, for example through VR peripherals such as HMDs or CAVEs, while relational architecture amplifies the participant to the building's scale, or emphasizes the relationship between urban and personal scale. In this sense, virtual architecture tends to dematerialize the _body_, while relational architecture tends to dematerialize the _environment_. (Similarities between virtual and relational architecture:) Virtual and relational architectures are not opposing practices, nor are they mutually exclusive. They are similar in that both are largely participant-centered, computer generated, and less expensive, permanent, sheltering and territorial than physical architecture. They are also fundamentally perspectivist (in Ortega's connotation of indeterminacy and interconnection, not in the Renaissance sense of priviledged vantage point): there is always a self-acknowledged point of view (POV) which underlines the partiality and performativity of the construction. In both virtual and relational architecture, the increasingly irrelevant notion of the "site specific", -which becomes an oxymoron in our age of non-location, is replaced by the notion of the "relationship specific". (Public becomes actor:) Relational architecture need not be inscribed within postmodern parasitic or symbiotic practice nor post-structural self-referentiality: it is not necessarily engaged in deconstruction, nor does it need to use the language or structure of the building itself. It distances itself from the notion of art in "public space" proposing instead art in "relational space" where the public becomes an actor, in the theatrical sense and in the sense of "taking action". Relational architecture events vindicate their synthetic, artificial qualities, and reserve the right to be effectist, improvisational and useless. (Search for behaviour:) But apart from special effects, beyond plasticity, the real motivation behind relational architecture is the modification of existing behaviour: the artist creates a situation where the building, the urban context and the participants relate in new, "alien" ways. The piece can be considered successful if the artist's intervention actively modifies the point of dynamic equilibrium between the public's actions and the building's reactions, and vice versa. There can be a variety of causal, chaotic, telepresent, predetermined, or emergent behaviours programmed into the piece and the uncertainty of the outcome is one of the main motivations for doing such a piece. (Precedents:) Although relational architecture is a relatively new field within media arts, precedents to the concept date back to ancient Greece (Simonides' discovery of mnemonics), and to the use of the Art of Memory in Chinese, Hermetic and Renaissance rhetoric traditions. In those traditions architecture was used as a repository of relatively-located memories which could be recalled by a speaker through a mental "walkthrough". A significant number of contemporary artists can also be said to have been, and continue to be, influential in the practice, among them Krzysztof Wodiczko, Archigram, Gordon Matta-Clark, Yona Friedman, Jenny Holzer, Rem Koolhas, the Situationists, Christian Moeller, Christo, Peter Greenaway, Vito Acconci, Dennis Adams, Knowbotic Research, Dan Graham, Cesar Martinez, Richard Serra and Rachel Whiteread. Rafael Lozano-Hemmer and Will Bauer are collaborating in the development of a series of relational architecture pieces to be presented over the next few years. The pieces entail the development of novel architectural interfaces using real-time computer graphics, 3D sensors, electro-acoustic music and robotic lights. The events, which take place after dusk, will be presented in half a dozen cities including Madrid, Linz, Graz, Barcelona and Mexico City. What follows is the description of the two pieces that have been realized so far. "DISPLACED EMPERORS" RELATIONAL ARCHITECTURE #2 September 1997, Ars Electronica Festival, Linz ============================================== A relational architecture piece was designed for the Ars Electronica 1997 Festival that transformed the emblematic Linz Castle, high above the Danube river bank. The intervention was called "Displaced Emperors" and its aim was to construct an interactive vector between two apparently unrelated historical oddities that link Mexico and Austria: the Mexican empire of Maximilian of Habsburg (1864-1867) and the "Penacho de Moctezuma", the Quetzal-feather crown of one of the last Aztec Emperors, currently housed in the Ethnological Museum of Vienna. The piece sought to involve the public in a web of power relations where history is seen as a virtual environment and identity is a performance sponsored by the myth of cultural property. The event took place at dusk and was controlled from the Rudolfstor gate at the Castle and from a makeshift souvenir shop set up near Hofberg street. 1) Architact ------------ Participants standing in the small plaza situated between the Castle's Rudolfstor gate and Hofberg street interacted with the Castle by pointing at it with their hand. A wireless 3D tracker calculated the direction of the participant's arm and a large, animated projection of a human hand appeared wherever he or she was pointing. When the participant moved his or her arm, the telematic hand followed, sliding over the Castle's facade, creating the effect of an amplified caress. Depending on where and how the participant "touched" the Castle, it transformed itself into Chapultepec Palace, the residence of the Habsburg Emperors in Mexico. The telematic hand "revealed" the Mexican palace as though it were inside the Linz Castle: the exterior became the interior. As the hand activated certain windows, music would be triggered and mixed in real time to produce the effect that the music was coming from that particular room. The "architact" interface allowed participants to read the building's media layer -a telematic braille that made perception a highly physical act. Maximilian and his wife Carlota were elected Emperors of Mexico by a small group of conservative notables who wanted to protect their interests against the national liberal policies proposed by Benito Juarez. With the help of Napoleon III's army, Maximilian, himself a liberal, took over the country in 1864 having been deceived over the amount of popular support that his regime would have. The story ends in tragedy with the withdrawal of the French troops and Maximilian's capture and execution in 1867, an event portrayed by Manet in a painting that Bataille called the beginning of the modern movement. Maximilian's body was embalmed and shipped back to Austria in the Novara: it now rests at the imperial crypt of the Church of the Capuchins in Vienna. During their empire the Habsburgs lived in a Spanish colonial castle, Chapultepec Palace, which they transformed so that it was reminiscent of their Palace at Miramar in Trieste. This Italian Palace, in turn, had several references to prior Habsburg palaces in Austria including the Schoenbrunn. The Austrian Palaces were themselves quoting a variety of classical stylistic archetypes. This "mise-en-abime" formed by palaces within palaces, was exploited in "Displaced Emperors" as a source of architectural samples to be mixed and remixed by the participant, who became a kind of deterritorial, detemporalized "architecture jockey". The vector of architectural transformation was also indirectly that of the displacement of power that the Linz Castle had experienced: from being the centre of Habsburg power during the Hungarian invasion of Vienna to becoming a passive museum-mausoleum serving as a repository for dead culture. The architact interface operated in between the seduction of the amplified caress on a harmless museum and the understandingly ambivalent reaction that some Austrians had when confronted with an interface that forced them to "salute" a building that Hitler had intended to use as his retirement residence. 2) Push Button Override ----------------------- At a makeshift souvenir shop near the Castle there was a computer monitor that showed the location of the architact participants with Orwellian precision. The monitor was beside a big bright red button clearly labeled "Moctezuma". For ten schillings (approx. one dollar) people could press the Moctezuma button and interrupt the architact interaction. The button would do three things: a) turn off all the lights except a searchlight with a "cultural property" symbol which automatically followed the participant who had the tracker; b) turn on a 35 metre projection of the "Penacho de Moctezuma" on the facade of the Castle; and c) trigger distorted Mariachi music. A few seconds after the button was released, the participants at the Castle could resume their interaction. The "Penacho de Moctezuma" is an Aztec headdress made out of the green tail feathers of the extinct Quetzal bird. Although there is no hard evidence that the Penacho was Emperor Moctezuma II's "crown", it is well known that it was the symbol of the most outstanding political and religious power in Pre-Columbian Mexico. According to one version of its history, the Penacho was given by Moctezuma to Spanish conqueror Hernan Cortes, who in turn gave it as a gift to Emperor Carlos I of Spain and V of Germany in 1519. In that same year Cortes captured and imprisoned the Aztec Emperor and a year later he died in mysterious circumstances: according to Indian witnesses Moctezuma was murdered by the Spaniards and according to Spanish sources he was stoned to death by rebel Aztecs he was trying to appease. Some historians believe the Penacho was passed from Carlos I to his brother Fernando who kept it in his art collection in the Castle of Ambras; other historians say it was purchased by Austrian Archduke Ferdinand in 1590. In any case, the Penacho was finally sent to Vienna and in 1878 it was taken out of the closet where it had been, folded and moth-eaten, for decades. The piece is now on display at the Ethnological Museum in Vienna. Mexicans believe that the Penacho is a very important part of their national identity: a piece with extraordinary emotional, cultural and symbolic value. Indeed, Aztecs assigned considerably more significance to objects made with feathers than with gold and silver. Many notable Austrians have expressed their desire to see the Penacho return to Mexico, among them Rudolf Burger, Carl Pruscha, and Peter Noever. These Austrians believe that the Penacho should be given as a gift to Mexicans as a symbolic gesture, among other reasons, to thank them for their protest in the League of Nations during the German annexation of Austria in 1938. When President Thomas Klestil declared in 1996 that he would look favourably upon the idea of sending the Penacho to Mexico as a demonstration of Austria's goodwill on the eve of the nation's millennium celebration, the Mexican government sent a diplomatic delegation to Vienna to deliver an official statement indicating Mexico's profound interest in obtaining the piece. Alas, a few months after this meeting, the Austrian Minister of External Affairs, Dr. Wolfgang Schuessel, sent a reply saying the Government regrettably could not send the object to Mexico for legal and conservation issues. The Moctezuma button was a causal, irritating 1-bit intervention which served as a metaphor for the simplistic, executive override features found in all complex control systems. The button was surrounded by mexican wrestling masks, fake penachos, plastic pyramids, velvet sombreros and other cheap cultural souvenirs. The Moctezuma button was a parody of the currency of cultural exchange, a moment of historical cynicism to question the colonial project, and a probe into the concept of "heritage". Is cultural property cultural poverty? "Displaced Emperors" ultimately proposed that rather than returning the "Penacho de Moctezuma" to Mexico, Austria should offer some Habsburg jewels as a romantic cultural exchange, and for the Penacho to become an integral part of Austrian identity. Technology: ----------- A custom-made GAMS ultrasonic 3D tracker monitored the vector formed by the arm of the participant. The position of the intersection of the vector with the facade of the building was calculated trigonometrically in real-time. Robotic light beams were directed toward the place of intersection by using the DMX512 protocol. Positional sampled sound was programmed so that it seemed to be generated at the location of the intersection. Custom-made software cued, triggered and controlled all audio visual events. A large 30 x 30 m etc pigi film projector was controlled via MIDI and using two precise electro-mechanic scrollers. The status of the Moctezuma button was relayed via MIDI.

"Re:Positioning Fear" used a web site, webcam, 3D trackers, and customized projection technology to connect a very specific instance of Austrian history and architecture with remote and local participants. The piece was loosely based on the Cathedral's fresco "the Scourges of God", which depicts the three Medieval fears of the people of Graz: the locust plague (which destroyed the fields in 1477), the Black Death (an epidemic that fortunately never had a devastating outbreak in Graz), and the fall of the city to Turkish invaders (which never happened). The fresco, which shows the oldest view of the city, has been ruined by inclement weather and incompetent restoration attempts, but is survived by a reproduction which can be seen at the Landeszeughaus. Using the fresco as a departure point, "RE:Positioning Fear" related several historical transformations and displacements of Fear, particularly as parts of the world enter a post-industrial, post humanist era. Re:Positioning Fear had two components: 1) IRC Sessions --------------- A program of Internet Relay Chat (IRC) sessions discussing salient "contemporary fears" featured thirty artists, theorists and critics from seventeen countries, some of whom also contributed texts used as conceptual background: Konrad Becker (Austria), Michael Boyce (Canada), Andreas Broeckmann (Germany), Steve Cisler (US), Vuk Cosic (Slovenia), Sean Cubitt (UK), Calin Dan (Netherlands / Romania), Erik Davis (US), Scott deLahunta (US / Netherlands), Robert Ehrlich (Canada), Maria Fernandez (US / Nicaragua), Paul Hertz (US), Margarete Jahrmann (Austria), Andreas Kitzmann (Canada), Ted Krueger (US), Diana McCarty (US / Hungary), Alain Mongeau (Canada), Gordana Novakovic (Serbia), Olu Oguibe (Biafra / US), Tetsuya Ozaki (Japan), Roc Pares (Catalonia / Mexico), Simon Penny (Australia), Susie Ramsay (Canada), James Sey (S. Africa), Pit Shultz (Germany), Amanda Steggell (Norway), Tank (Canada), Nell Tenhaaf (Canada), Mark Tribe (US), and Faith Wilding (US). There were six loose thematic threads: FEAR AT THE END OF GEOGRAPHY - delocality; cultural tectonics; border wormholes; tourist clones; placeless vs. multiplace; refugees and refusees. FEAR AT THE END OF BIOLOGY - body DJs; human genome and other endotaxonomies; microbesoft and biotrademarks; dividuals. FEAR AT THE END OF ARCHITECTURE - vampire buildings; special effects home; architact; site-specific isn't; the internal exterior; domesticity. FEAR AT THE END OF ART - resistance of net content; bandwidth denial; retrofunding; the long wait; the search for otherception. FEAR AT THE END OF TECHNOLOGY - cibernating; baby walkmans; persistance of the humanist cyborg; all intelligence is artificial. FEAR AT THE END OF "THE END" - paranoia and postnoia, St Augustin, apocalapsus, nanohope. During the Film+Arc Festival, the IRC sessions were projected in real-time on the Zeughaus arsenal's courtyard facade; two Barco 9200 projectors covered a total area of 15 x 20 metres. The building was thus taken over by a deterritorialized dialog or "source code", creating a "building with subtitles". A webcam captured the event every second and allowed the internet participants to see their contributions as they appeared on the building. The IRC sessions reflected on contemporary fears as decentered, distributed phenomena or "syndromes" more than invasions: global warming, AIDS, terrorism, economic violence, surveillance society, genetic tampering, refugees, etcetera. This mirrored the nature of IRC text which does not have a clear textual "backbone" but is rather composed of textual "ribs". The proceedings of the IRC sessions, in the form of slightly-edited logs, can be found in the "Re:Positioning Fear" web site, where participants also submitted notes, quotes, and other texts that anchor the discussion on FEAR from the realm of the abstract to very specific instances within geopolitical, architectural, philosophical, biological, etc discussions. 2) Tele-absence installation ---------------------------- Even though the IRC sessions could have been projected on the arsenal by covering most of the facade, an interface was designed to prevent all of the text to be visible at one time. The interface was called "tele absence" and it consisted of an "active" shadow that revealed the text on the building. To read the building, a participant standing in front of it had to wear a small wireless sensor and walk around the courtyard. As he or she walked, two pigi 7kW Xenon light sources tracked his position and projected his shadow onto the facade of the Zeughaus. By using robotic lighting control, the shadows were focused dynamically so that regardless of the participant's proximity to the lamps the shadows were always crisp and well defined. The final effect was a "dynamic stencil" whereby the shadow of the participant was an architectural element which "revealed" the IRC texts that appeared to be within the building, as though the shadow was a cutout or an x-ray of the building. "Tele-absence" was defined as the technological acknowledgement of the impossibility of self transmission. Tele-absence was proposed as a celebration of where and when the body is not. The shadow was not an avatar, an agent, nor an alias of the participant's body, it was remote absence, the exclusion of the body, effected through the body-double, the cut-out, the not-transmitted, the shadow. The tele-absence interface benefited from the impossibility of positioning the body within its shadow. Just as contemporary physics has discovered that a vacuum is indeed a place with intense quantum mechanical activity, here the shadow, a supposedly immaterial form created by the absence of light, became a site of telematic activity. As it traveled over the building, the shadow was deformed by the windows and crevices of the facade as well as by the characteristics of the movements of the participant. This added to the anamorphosis of the projection and underlined the building's performative quality. By calculating when, where and how the shadow intersected the Zeughaus, the installation's computers triggered audiovisual events which used the texts contributed by the people on the IRC sessions. The piece emphasized the fact that the shadow is formed by a collaboration between the light, the building and the participant. A shadow interface could be interpreted to be a metaphor of the obliqueness of ancient (and contemporary?) threat. The Zeughaus itself was built out of fear of the expansionist Turks: yet their looming presence was felt only as a shadow, as they never entered Graz. Here, the Zeughaus became a repository that performed the transformation and the repositioning of the fears.
