Constraint Mexico

Exhibition — gordo @ 7:35 pm

Constraint City is taking part in Transitio festival in Mexico between 25.9 – 4.10 2015. There’s a Constraint city walk planned on Saturday 26.9 at 5pm in front of the Coyoacan Hotel. Here are the exact coordinates:,-99.1624334,16z

For the first time I am going to use the Constraint City Android app with new servo motors from Dynamixel / Robotis from South Korea and a completely redesigned corset with 3d-printed parts to make the constraint walk even more “pleasant”.

Constraint City took part in the exhibition “Sensing Place. Mediatizing the Urban Landscape” which compiled the Crème de la Crème of artworks/designs dealing with the augmentation of electromagnetic signals in our urban environment. Works by Mark Shepard, SENSEable City Lab and Christina Kubisch are featured, just to name a few. In the words of curator Sabine Himmelsbach, the exhibition seeks to address this reconfiguration of the public space by means of an increasing overlap of the digital spheres of information and geographical reality.

As part of the show, the House of electronic arts Basel organized a handful of city walks with participating artists and

Oscar Abril Ascaso invited me to participate in his project Techformance which will take place around Murcia/Cartagena and will eventually be  shown at ARCO Madrid, one of the biggest art fairs in Europe.

I’ve been invited to do a public performance with some citizens from Cartagena interested in trying out the Constraint City jacket in January. It was an interesting experience watching other people than me :) wearing the corset.

Around eight people (3 women among them!) wore the corset and subjectively experienced an enhanced psycho-geographic walk through emblematic signs and ancient monuments in the maritime city of Cartagena!
The walk has been recorded and each progressively attacking network has been rendered into a Constraint City map of Cartagena.

A hub of participatory projects inviting visitors to the art fair and citizens in Murcia alike to take part in real time from February 11th to 16th 2009. All other selected works are presented on the Techformance website (both in english and Castellano). Take a look and contact me if you are around Madrid. I’ll be there from 11th till 13th of February!

The project “the pain of everyday life” is a city-intervention and a digital art performance addressing public and private space within the realm of everyday constraints. It resembles an urban interface for an invisible city, an architecture which is subconsciously perceived and which constantly oscillates as resonant landscape, consisting of electromagnetic waves.

A chest strap (corset) with high torque servo motors and a WIFI-enabled game-console are worn as fetish object. The higher the wireless signal strength of close encrypted networks, the tighter the corset becomes. Closed network points improve the pleasurable play of tight lacing the performer‘s bustier. Thus, constituting the aether as a space of possible pregnancy, filled with potential access-points to the networks of communication. Everyday walks between home, work and leisure are recompiled into a schizogeographic pain-map which is fetched from GoogleMaps servers with automated scripts. By wearing the straight-jacket, the artist not only writes, but is at once also able to read the city code.

The outcome of his walk provokes an emergence of a city-shaped body. The map keeps not only tracks of all wireless networks along the route, but also the wearer’s détournement when entering a very dense network place, a so called pleasurable pain zone. Therefore, the artist becomes the 21st century flaneur who balances along sensual perceived pain and the torture of everyday routes in a very special Arcades Game Project.

After rendering a 6000x4000pixel map from GoogleMaps using 256×256 image tiles, my script started to fail every time. What seemed like a strange bug, turned out into a (once again) google restriction … OBEY!


Even after changing my IP and surfing through another Proxy with a sp00fed MAC-Address, i received the error. :/

Wikipedia says about the 403 error:

The message may be thrown up by conventional searches or links; the suggestion that the user’s computer may be infected is often incorrect. The screen was first reported

in 2005 and was a response to the heavy use of Google by Search Engine Optimisation companies to check on ranks of sites they were optimising. The message may also be triggered by high volumes of different searches from a single IP address. The block is removed after a day.

Theory — admin @ 5:38 pm

“The pain of everyday life” is a critical performance addressing public and private space and their paradigm shift in the realms of everyday constraints, therefore the relation of abstract information layers to our everyday life. Within urban systems, as we are experiencing them right now, an invisible architecture is perceived and superimposed

sildenafil on line

which constantly re-assembles a resonant landscape, consisting of electromagnetic waves. It bypasses human, buildings as well as vehicles through the streets of a so called Maxwell City. The restriction as such and its augmented invisibility are the source material for Gordan Savicic.

A chest strap with high torque servo motors (muy fuerte mi amigo!) and a wifi-enabled gaming console (Nintendo DS lite) are worn as fetish object. Thus, when approaching an enclosed encrypted wireless network, the strap reacts immediately. The higher the wireless signal strength, the tighter the jacket becomes. This technique, also called Inverse War-Driving, challenges the much overhyped discourse about locative and wearable media. Everyday walks between home, work and leisure are recompiled into a schizogeographic* pain-map. The 21st century flaneur balances along sensual perceived pain and the torture of contemporary Arcades sans fil.

Michel de Certaeu stated about citizens and their everyday movements:

They walk – an elementary form of this experience of the city; they are walkers “Wandersmaenner”, whose bodies follow the thicks and thins of an urban “text” they write without being able to read it. These practitioners make use of spaces that cannot be seen.(2)

By wearing the straightjacket, the Wandersmann not only writes, but is at once able to read the city code. Electromagnetic waves are forming the chest strap, thus shaping the invisible architecture directly onto the human body. As another countermove the mapping procedure is recorded on a GIS-layered map which keeps track of ordinary everyday walks and its chosen alternative routes. By displaying the playful approach of the wearer, it reveals not solely a psychogeographic pain-map, but as a result also the wearer’s admiration for gentle tortures as well as the alteration of everyday routines in RealPlay.

It is always by way of pain one arrives at pleasure. (Marquis de Sade)


Theory — admin @ 1:06 pm

Das urbane System des 21.Jahrhunderts ist von einer unsichtbaren Architektur ueberlagert, einer Landschaft komponiert von elektromagnetischen Wellen, welche um sich greifend, Menschen, Fahrzeuge sowie Gebaeude durchdringt und in Resonanz versetzt. Diese elektromagnetische Umgebung ist die Ausgangslage sowie das Material fuer das Projekt “The pain of everyday life”. Die Unsichtbarkeit formt die Relation zwischen abstrakter Informationsarchitektur und Alltagsbeschraenkungen, wobei letztere durch eine speziell angefertigte Jacke koerperlich erfahrbar gemacht wird. Die Jacke (wearable computer) besitzt eine portable Spielkonsole, die mit Wireless Funktion ausgestattet und fuer dieses Projekt speziell modifiziert worden ist. Die Programmroutine der Konsole “scannt” permanent nach drahtlosen Netzwerken, analysiert deren Zugangsbeschraenkung

und formt anhand der empfangenen Daten die Corsage am Koerper. Das Brustkorbgeflecht der Jacke ist mit High-torque Servos ausgestattet. Je staerker die Verschluesselung und dichter das Signal, desto enger die Manschette und infolge, desto schmerzhafter bzw. unertraeglicher wird das Bewegen durch die unsichtbare Maxwell’sche City. Der Alltagsweg zwischen Arbeit, Zuhause und Freizeit wird re-kompiliert; der Flaneur des 21. Jahrhunderts balanciert entlang des lustvoll-rezipierten Schmerzes und der Qual in den zeitgenoessischen Arcades sans fil(1).

Funknetzwerke sind das Geruest der ubiquitaeren Datenkommunikation und machen das Internet allgegenwaertig, wobei Privat und oeffentlicher Raum nicht mehr im herkoemmlichen Sinne existieren, viel eher in eine Parallel-welt ko-existieren, welche zwar nicht sichtbar aber sehr wohl spuerbar ist. Privatraum in drahtlosen Netzwerken wird durch Verschluesselungsalgorithmen und Zugangsbeschraenkungen definiert. “Ausgeschlossen sein” bedeutet nicht nur Behinderung im Zugang zum oeffentlichem Raum Internet, sondern eben auch einer nutzlosen elektromagnetischen Strahlung ausgesetzt zu sein.

Michel de Certau schreibt ueber die taeglichen Bewegungen von Menschen in urbanen Systemen (1984):

They walk – an elementary form of this experience of the city; they are walkers “Wandersmaenner”, whose bodies follow the thicks and thins of an urban “text” they write without being able to read it. These practitioners make use of spaces that cannot be seen.(2)


Auf aehnliche Weise artikuliert sich das Projekt von Gordan Savicic, jedoch wird es dem “Wandersmann” ploetzlich moeglich den Code der Stadt zu lesen, indem unerreichbare Wege der Funkkommunikation direkt auf den Koerper Einfluss nehmen. Der modifizierte Koerper ist der Balance-Act aus Schmerz und Vernunft. Im Gegenzug werden die geschriebenen Wege auf der Spielkonsole mitaufgezeichnet. Das Bewegungsmuster ist der neue Code, den die Stadt beschreibt und wird auf Papier als Momentaufnahme einer prozessuralen Datenarchitektur wiedergegeben. Die Karte ist somit die Inschrift eines psychogeographischen Schmerzmusters, sowie Traegermaterial fuer eine Reihe von Publikationsbeitraegen von u.a. Florian Cramer (GER), Femke Snelting (BE), Margarete Jahrmann (A/CH) und Martin Howse (UK) zu RealGaming, Corsagen und Walking Practices. Die Publikation wird im Format eines Stadtplanes erscheinen und Teil der Ausstellung.
