Attending Machine | 2015

+ Museum fΓΌr Angewandte Kunst, Frankfurt, Germany
+ Herzliya Museum of Contemporary Art, Israel
+ Bloom Awards, Art Fair Cologn, Germany
+ Gwangju Media Art Festival, South Korea

At times dominated by constant exposure to social and personal information, FOMO (Fear of Missing Out) conditions our need to ‘attend’ virtually, as a statement, even more than to ‘be’ in the physical domain.

Attending Machine temporarily visualizes a feed of portraits taken from Facebook accounts. The participants have agreed to take part in a virtual Facebook event named ‘Donate your virtual identity to art’, only to be actualized within the machine.

The machine writes on a wall painted with an ultra-violate sensitive pigment. While passing over the surface, it turns on and off 96 UV LEDs in a carefully timed sequence, exposing the surface to UV and temporarily creating dots and dashes on the surface. Those are added, creating the ephemeral images.

The work questions the possibility of personal connection and intimacy on today’s digitally connected world. The Facebook platform is used as a case study from which data is collected. The attendees’ profile images are printed and fade as time passes. The portrait is no longer eternal and is based on the way the person depicted chose to represent him or herself in the social network. One by one, the images appear and fade away.

The act of printing makes each individual identity present for a moment within the masses. The ephemerality of the images poses questions: What is the point in an identity representation in the digital age and why do we so desperately want to be seen and ‘liked’ within the feed? Are we just another statistic in the virtual space? The Attending Machine aims to slow down our accelerating life stream, and to enable a technological poetic reflection on the state of being.

People You May Know

Israel Museum, Jerusalem, 2015 | Bonn Bundeskunsthalle Museum, 2016

The sound installation People You May Know consists of a collection of audio speakers hanging in the gallery space, playing monologues taken from personal Facebook profiles of the artist's friends. These sentences that she reads, using the first person form, are personal and revealing. The voice moves in space in a way which is determined by an algorithm generating the movement course in real time, creating a feeling of a speaker walking in the gallery.

The site specific installation was part of the group exhibition ‘Brief History of Humankind’, Israel Museum, curator: Tania Coen Uzzielli

The work was originally exhibited as part of the solo exhibition People You May Know at Hansen House, Jerusalem, 2014.


Scattered Light | 2015

@ National Museum of American Jewish History, Philadelphia

Scattered Light visualizes reflections of museum visitors on the concept of ‘freedom’. It uses a selection of videos taken from the museum’s ‘It’s Your Story’ recording booths video database, where visitors are recorded sharing their associations on ‘freedom’.

A machine rides along a 9 meter rail, printing selected sentences and frames from the video collection. The printed faces and texts fade away as time passes, pointing to temporariness and fragility.

The machine writes on a large wall painted with an ultra-violate sensitive pigment. While passing over the surface, it turns on and off 96 UV LEDs in a carefully timed sequence, exposing the surface to UV and temporarily creating dots and dashes on the surface. Those are added into texts and images. Once a visual is printed, the machine turns and prints a new one on it fading memory.

Scattered Light was commissioned by National Museum of American Jewish History, Philadelphia (January 2015)

People You May Know | 2014

Curator Karni Barzilay | 6 Dec 2014 - 16 Jan 2015

Curator Text:

Currently, the way we consume knowledge and information about people around us has changed. Our technological reality has created a distanced from the human-personal experience, translated into algorithms, codes, shapes, and is more mediated than ever. This change enables exposure to massive amounts of varied data; it is also a tool through which to study today's human behavior. New Media theorist Lev Manovich sees the emergence of social media in the mid-2000s as an opportunity to study social and cultural processes, through the ability to read and comment on, listen and follow the opinions, ideas and feelings of hundreds of millions of people, where there is no need to ask their permission.

In the past, social and cultural studies relied on two types of data: Surface Data, which is about lots of people, and Deep Data, which deals with few individuals or small groups. The first approach was mainly used in fields and methodologies that adapted quantitative data analysis such as statistics and mathematics. The second approach was typical of humanities and used for the fields of literature, arts and history. With the rise of social media, along with the development of computational tools that can process massive amounts of data, online information has become a database for social study, in which it is no longer necessary to choose between quantitative and qualitative methods. Today it is possible to learn from knowledge and insights created by a mass of people, which are available via the internet, thus to combine the two study approaches and their underlying types of data.

Liat Segal's first solo exhibition deals with the relationship between the human and the technological, as well as the way the self is represented in social media. The exhibition consists of four installations that light up the question of a personal dimension in a technological environment and the relationship between human and mechanical behavior. Segal's works combine components and elements of mechanics, software and electronics, which are influenced by the field of software and big data analysis, her previous fields of occupation. She uses these to examine the tension between the quantitative and content-related approaches, between the general and the unique, between the masses and the individual.

The title of the exhibition – People You May Know is drawn from Facebook's suggestion to its users, to connect with other users in order to expand their circle of friends. As a rhizomatic data mechanism operating by the principle of interpersonal connections expansion, this Facebook suggestion raises questions about the types of relationships and our identity's definition within Facebook. Segal's quest for the possibility of personal identity, personalization, and intimacy to exist on the internet, has led her to use the Facebook platform as a case study as well as a field of study from which she samples data for her works.

The sound installation People You May Know consists of a collection of audio speakers hanging in the gallery space. Each playing monologues are taken from personal Facebook profiles of the artist's friends. These sentences that she reads, using the first person form, are personal and revealing. Segal acts as a researcher, processing and categorizing the texts as social data in a pseudo-scientific "experiment" of profiles identities and narratives identification and appropriation. She thus creates a process of a new identity formation which is composed of multiple voices and narratives sampled from Facebook.

The voice moves in space in a way which is determined by an algorithm that chooses the movement course in real-time, it creates a sense of a speaker walking in the gallery. Although the voice lacks body or identity, it does have a location in space, which is represented in the work Location 2.0 exhibited in the adjacent space. Using shining objects that are originally used as a survival rescue blanket to maintain body temperature, this work represents a mathematical graph of the voice movement in space. The objects hanging on the wall are inflated in accordance with an x and y-axis system while pointing to the location of voice in space. Although she uses a mathematical model that supposedly represents the world, the model's physical expression is very much momentary, made of air.

In the installation Writing Machine, a computerized machine is drawing with a paintbrush and water on the gallery floor. Repeatedly and endlessly, the machine scribbles names taken from the artist's list of virtual friends. One by one, the names are written down and then erased (evaporated). The act of drawing makes some of the individual identities present for a moment within the masses while revealing an additional layer to Segal's entire process in this exhibition – the destruction and reconstruction of identity representations. The mass of cylinders, installation Placeholder at the Hansen House patio presents a coded image – the well-known Facebook face icon. This image is made of a surface covered with roll-shaped bodies, originally used as a cosmetics product packages, dark on one side and silver on the other. Together, they create an entire image, a sort of material translation of pixels, where in one particular moment and location of the spectator's sight, this translation consolidates into a generic face. The well-known face icon represents the moment when we join Facebook, the first step of identity construction in it. That very "determining moment" when we change this generic image into our own profile picture poses a question: Have we turned from an icon into a private person, or are we just another statistic in the virtual space?

Sand Printer | Future Regressives | 2013

Future Regressives are futuristic fossils drawn by a mechanical printer on a mixture of sand and salt. These fossils contain many details, as if they were drawn by an extremely accurate and never fatigue hand.
In contrast to the past fossils, the future regressives have a short memory. Once drawn they will be easily erased, allowing new visuals to appear and be forgotten.

Sand Fish stop motion animation | Digital images are physically drawn by the printer. The sand prints are photographed and returned to the digital space in the form of stop-motion animation:

Sand Printer was built for the Venice Biennale 2014 Israeli Pavilion in collaboration with Guy Hoffman.


Confession Machine | 2014

The Confession Machine prints online texts that fade away as time passes, just like the confession itself. The machine prints on a surface painted with an ultra violate sensitive pigment. While passing over the surface, it turns on and off 16 UV LEDs in a carefully timed sequence, temporarily creating dots and dashes on the surface. Those are added into letters, words and sentences.

The intimate and revealing printed texts are taken from social networks, showing the lightness of confessions via online channels today. People today willingly share personal details of their lives via the digital medium. At the same time the importance people give to online confessions is small and temporary in its nature. One sees a reviling status, may get excited, like, comment, even share, and forget it. That is the life cycle of an online confession.
It is also a paradox as all this personal information now stays on a virtual limbo, forever exposed.

The Confession Machine uses the technology of repeatable writing using light (developed by the Bloomfield Science Museum Jerusalem) to show the temporary nature and lightheadedness of online confessions. A confession is printed and fades away. A new confession immediately takes our attention. Sometime a confession starts fading ever before the entire sentence was completed.

The Confession machine was commissioned by Artists' Residence Herzelya, January 2014.

Wall To Wall Carpeting | 2013

by Liat Segal & Shahar Binyamini
Dancers: Iyar Elezra, Shamel Pitts

Three hundred liters of paint are slowly flowing through the dance studio, changing the space. The change is so slow that it is hard to notice at any single moment. As time goes by, however, one may suddenly realize that the world has completely changed.
The work was presented for the first time as part of Plaza 2013 at Bat Sheva Dance Company.


Microfilm | 2014

@ Elsewhere Gallery by Adi Dahan | Herzliya Museum of Contemporary Art

Elsewhere Gallery is a temporary gallery founded by Adi Dahan under the exhibition "Rising Star" in the Herzliya Museum of Contemporary Art. The gallery itself operates outside the museum walls and is being broadcasted back to museum through a web video call.

The work is making use of two machines built by Segal; the first (Heart for the tin man, 2012) is a painting machine, dropping acrylic paint on the surface below it at precise amounts and positions. The machine was used for painting in response to voices and music that surrounded it. This work results in a series of paintings, each one originated by a different source of information. While the paintings seem chaotic they actually have structure. As in many cases, the alleged randomness is a result of a sequence of strict choices.
By minor changes to the machine settings and replacing its painting device with a macro lens camera, the painting machine transforms into a scanner, scanning its own former outputs. This second machine results in the video work. The scanner navigates along the paintings as if they were a map and the paint drops were a topographic landscape. The macro lens reveals details that are invisible to the naked eye, some of which look as if they were taken by a lab’s microscope.

The new system works in interaction with museum visitors. Visitor’s motions are captured by video, affecting in real time the scanner’s navigation as a physical-human remote control.
The flow in this work is circular. Digital data gets a physical-mechanical manifestation, then sampled back into the digital world.

The name of the work “Microfilm” implies the analogue data storage mechanism that was in use before today’s digital data storage systems. Segal’s machine gives a strong association to the movements, magnification visuals and sounds of the old school microfilm reader.


Hatch | Amsterdam Light Festival | 2013

by Liat Segal & Hagar Elazari

The Hatch is a peephole to endless inner depths. It's a kinetic light sculpture half buried in the ground. Standing afar, it looks like a transparent cube covering illuminated sticks resembling a ladder. When looking from above, one sees an endless tunnel to the bottom of the earth.
The Hatch is manipulating space, building an infinite chamber through light.

The work was commissioned by the Amsterdam Light Festival, December 2013 and by the Jerusalem Light Festival, June 2014.

The sculpture is placed between a mirror and a half transparent mirror, behind which the viewer stands, seeing endless reflections.


Heart for the Tin Man | A Show of Robotic Action Painting & Music | 2012

by Liat Segal & Assaf Talmudi

Does a machine, any machine, create alienation just by virtue of being a machine? The answer, as far as we are concerned, is negative. The performance Heart for the Tin Man is a celebration of homemade machines, which have nothing to do with usefulness or usability – in the sense we usually attach to these terms.

At the center of the performance stands a large robot, painting enormous abstract paintings in acrylic. The robot paints on a large canvas in response to the human voices and musical instruments that surround it. The audio and visual structures are open, and only subordinated to the interaction between the robotic parts and the human playing.

Heart for the Tin Man was the opening show at Fresh Paint 5.

During the show Assaf Talmudi (accordion), along with our special guests Shlomi Shaban (piano) and Ronald Boersen (violin), played music which in turn activated the painting machine and twelve robotic drums.

The sound was translated automatically at real time to movements of the painting machine and the release of acrylic paint by four pumps.


The Originals Factory | 2011

The Originals Factory is a fusing together and questioning digital, mechanic and plastic approaches to art, abstraction and originality. It is basically a DIY robot, built and programmed to create landscape paintings in the style of American abstract expressionism.
The computer system uses real time video input to control motor movement and pump actions to release paint drops on a large canvas. The drops are then drawn downwards courtesy of gravity, leaving thin colorful line marks.

The Originals Factory was first presented at the DLD Tel Aviv conference in November 2011.

The graphical language achieved by this mechanism is a language of lines. Instead of pixels creating the image, we get vertical graphical units, or Vixels.
Our mechanism allows us to control a few parameters for each such Vixel; its Horizontal position, length and color.

Other types of online data were used for prints, such as Google Trends and real time generated surveys.

Cellular Graffiti Printer | 2011

What if people would expose and visualize their SMS text messages on buildings? If your Facebook status would be printed on a real, physical wall? What if you really checked in when you check in?
The wall printer takes the wall status concept back to physical dimensions.
Wall Printer
Inspired by old-school pin printers, the wall printer is a manually held device using seven markers to print digital messages on any flat surface. Seven individually controlled servo motors move the markers up and down, drawing dots and dashes.
When you manually slide the printer over a wall, the servo motions are carefully timed to produce text messages.

Connected to a cell phone, the printer can be directly fed by SMS text messages, Facebook statuses, GPS coordinates or practically by any other digital data source.
It uses a IOIO board to connect the physical electronic parts to an Android device and control them from an Android application.

This project was done with help and advice by Ytai Ben Tsvi, IOIO inventor and friend :)

Robotic drums party installation | 2011

Robotic drumsticks were playing on steel barrels at an abandoned textile factory party, Bar Yochai, Tel Aviv.
Beats were generated automatically, at real time, according to the music played by the DJ.

The system listens to the music played, analyses it and controls the drumstick's beats accordingly.
People choose which drumstick play at any given time by making shadows on them.


Robotic Drums | 2010

by Jonathan Rubin, Liat Segal & Assaf Talmudi 18 Darbuka drums and 36 robotic arms are controlled via wireless communication. Drum music is composed and played at a music sequencer on an iPad.

The project was presented at the Bat-Yam international biennale of landscape urbanism, September 2010, as a part of the 'Green to Blue' ecological street project, by Matanya Sack and Uri Reicher. During the biennale, electricity generated by wind turbines and photovoltaic cells was used to operate the robotic Darbuka drums. The drums were mounted on the wind turbines columns, creating a hybrid, digital-mechanic drumming circle, a futuristic-traditional acoustic space.

Thanks to Ben Handler and Eyal Talmudi for playing with us! :)

The making of...

So, what do we have here... 18 darbuka drums, each drum is played with two sticks mounted on servo motors and is lit by a super-bright 1W LED. We chose to use drum sticks mounted on servos (rather than the traditionally used solenoids) in order to achieve a powerful sound accompanied by a visual effect of a drumming circle.

Each of the 36 servos and 18 LEDs is controlled independently in real-time. In order to play (and light) our drums, we needed to control 54 channels wirelessly. To this aim, we built nine control units, each consisting of an Arduino and a XBee radio transceiver. Each unit was designed to control two drums (4 servos and 2 LEDs):

Two digital servos with attached drum sticks and a super-bright 1W LED were installed on each of the 18 Darbuka drums

A master netbook, running Max/MSP, sends control commands wirelessly (via XBee radio transceiver) to all control units.

As a final touch, we added an iPad interface to give an easy and intuitive way to interact with the installation. OSC protocol was used for wireless communication between the master netbook and the iPad (via Wi-Fi).

Three modes for playing the drums in real-time have been designed. The Sequencer mode allows composing specific beats for each of the 36 drum sticks. At this mode users can design and play loops and when happy with a loop, save it as a preset. Users can shift between previously saved presets at Presets mode.
Users can also play the drums by 'hitting them' at a location based Intuitive jamming mode.

At both the Sequencer and the Presets modes, the user can control the BPM of the loop by either switching a dial or shaking the iPad at the desired tempo.
Additionally, the user can switch between parts of the loop (and either play the entire loop, 1/2, 1/4 or 1/8th of it).

Non Newtonian Fluids

Rivers and creatures of cornflour vibrated on speakers...
Non Newtonian fluid Non Newtonian fluid

Or as wiki describes... "A non-Newtonian fluid is a fluid whose flow properties are not described by a single constant value of viscosity"...

DIY Multi touch screen

Our low cost multi touch screen was built using the frustrated total internal reflection principle.
Total reflection occurs when light travels from a medium with a high refractive index to a medium with a lower one. The light is then trapped within the first medium.
In our case the Infra-Red beam of light, transmitted by IR LEDS, remains trapped inside an acryl surface, since the refractive index of the acryl is higher than that of the air surrounding it. When touching the acryl surface, light bounces off the finger out of the surface.

The touch-screen is composed of an acryl surface, a standard projector connected to a PC, a mirror, an IR-sensitive webcam and a foldable, portable construction:

The acryl surface is used both to display the PC output and to sense user's input.
The acryl is coated with diluted silicon which enhances the amount of reflected IR light due to user's applied pressure on the screen.
Then, a sketch paper sheet is placed on the silicon layer to protect and isolate it. A diffusing material is layered on top of the sketch paper. The diffuser is semi transparent, allowing quality projection, on the one hand, and blocking access visible light from the other side of the screen.

The entire surface is framed with an aluminum frame which has 112 IR LEDs drilled into. The LEDs' tips, sticking out of the frame, are coated with black silicon. This is done to reduce IR light spilling in the wrong direction.
To keep everything together and protected from short circuits, a wooden frame is applied around the screen.

The 112 IR LEDs in the aluminum frame are divided into 14 sub-circuits, each containing 8 LEDs and one resistor. The 14 sub-circuits are connected in parallel, producing a circuit that consumes 1.4Amps and 12Volts. It is powered by a standard PC power supplier which is short circuited to work without a motherboard.

The reflected IR light is detected by an IR-sensitive webcam. We used the Microsoft VX-1000 webcam. To make the camera sensitive to IR light we removed its internal IR Filter. To make it insensitive to visible light we applied several layers of burnt camera film.

This project was done as a part of the Out Of the Box Week #IV at Microsoft Innovation Labs, Israel, by Hen Fitoussi, Kfir Karmon, Omer Ramot & me.
