Fresque #1 - Presentation

A monumental fresco in public places between France and Japan....
The electro-video artist Lionel Palun proposes with Fresque#1 a monumental fresco, broadcasted through two giant screens located in public places - one in France, the other one in Japan.
The artwork will bring into resonance these two distant places through a video feedback principle -one of the artist’ trademark - mingling infinitely as mirror images two simultaneous video recordings from both countries. What can arise between these spaces inhabited at different times of their respective lives, taking into account the time lag ?
Train station, airports and other public places are places of transition, of expectation, where it is common to dive into a solitary activity, isolating ourselves from others. The device will allow passers-by to participate randomly to an experience that puts them in connection with people in the same situation but geographically distant. What we are building here is a form of co-presence. The work is thus both similar and different between the two countries, playing with the illusion and contemporary myth of

...playing with urban data to which it gives shape...

Fresque#1 is an interactive digital fresco that Lionel Palun creates with today’s brushes : video, networks, real-time algorithm, the Internet and data flow. Several types of data will indeed be used to generate in real time
an abstract visual score that will modulate the loop of images between France and Japan.
Fresque#1 proposes thus a sensitive approach of the data via a shared and hybrid image, which materialize into an artistic form an urban breath, the invisible threads pulled by the city. Lionel Palun questions us through this artistic installation on the poetry that can emerge from human and data flow that intermingle.

...and inhabitated by passers-by with whom it interacts.

This evolutive and abstract fresco will also be populated by the audience as it passes by. The artwork indeed feeds with the silhouettes from travelers as well as from elusive appearances of portraits that are being randomly captured and that immediatly scatter into a system of particles that follow the people’s movement. The audience thus becomes the artistic raw material of this artwork, bringing it into life by its own presence and driving its evolution.

An artistic installation generated through an arts & sciences research process

The consortium of Europe + Japan project FESTIVAL has invited Atelier Arts Sciences to join this project through the organization of an arts & sciences residency with the artist Lionel Palun.
The project Fresque #1 was imagined within this collaboration.
FESTIVAL is a collaborative project (Nov.14-Oct.17) led by CEA-Léti and gathering 7 Japanese partners and 7 partners from Europe (France, Italy and Spain) and supported by the European Commission (H2020 project).

FESTIVAL project’s vision is to provide IoT experimentation platforms providing interaction facility with physical environments and end-users, where experimenters can validate their Smart ICT service developments in various domains such as smart city, smart building, smart public services, smart shopping, participatory sensing, etc.

Creation/Touring : The artwork will be created in Nov. 2017 between France and Japan.

First prototypes connecting two nearby places have been created and presented successively in Tuba (Lyon – June 20th 2016), EXPERIMENTA Fair (Grenoble, 5-8 October 2016).

The artwork has also been designed to be adapted and presented afterwards in several places and festivals, recreated each time according to the spaces it will invest and connect. The artistic installation will thus embody, in a certain extent, the identity of the cities or districts that will welcome it.

Both as an artist and as a citizen, I wonder what is left of our individuality and our freedom in a public place overloaded with video cameras and sensors, all connected to the several heads of a mysterious hydra to which we give several names : big data, learning algorithm, Internet of Things...
When Atelier Arts Sciences offered me to be the artist associated to a research project between Japan and Europe on Internet of Things and smart cities, I got very excited by the opportunity to get closer to it and try to understand it better. The foundations of the artistic installation Fresque#1 lays in this very curiosity.

It is driven by the idea to reverse some of the components of the world of data :
• Video cameras are usually hidden in public places, their images are being stored and analysed without awareness and control from passers-by. Fresque#1 will, on the contrary, show video cameras and what they are fiming.

• Images and data that we produce are massively stored, analysed and/or reused. Here, Fresque#1 does not record anything. All data, images or videos are immediatly digested and dissolved into a giant live brodcasted image.

• Captation from photo portraits is the data that is perceived as being the most sensitive, deeply related to our identity. And yet, it actually doesn’t really interest networks that rely more on associated metadata. Fresque#1 plays with this paradox by displaying and then engulfing right away
faces from the audience within the video stream. The few pixels of the faces mingle into the mass of data in a constant loop between the two locations presenting the installation.

• While newtorks propose to abolish space and time, Fresque #1 twists the fake digital ubiquity by proposing an interaction that doesn’t deny the geography separating the two connected spaces.
Fresque #1 challenges thus several contemporary myths through an interactive digital fresco created with today’s brushes : video, networks, giant screens - while assuming a high graphical aspect.

1. General principles of the installation
Fresque#1 takes the form of constant video feedback between the two places, enriched by two types of data : video capture of spectators passing in front of the installation and real time data provided by sensors located in the installation area of close by.
Neither the data related to the spectators nor the video stream are being recorded.

2. The principle of video feedback
The principle of video feedback is to capture the broadcasted image. In analogy with audio feedback, the video camera replaces the mike and the screen replaces the speaker.

In Fresque#1, the video feeback is dual. An image is captured in one place, broadcasted in the other place, captured again and broadcasted again in the first place. We thus obtain a continuous and real time loop between the two places.

3. Feeding video feedback with data
Data are used to create a live graphical score inlayed in the double video feedback stream. No image is being recorded.

3-1- Data collected by sensors linked to the public places

Several data related to the public places (uses of public transportation, passenger flow, electric consumption, meteorological data...) will be used to generate real time and abstract graphical score :

3 screen shots of the graphical score at 3 different times

To embody the breathing of a public place, Lionel Palun will select sets of dynamic data that will bring life to its image. These data must evolve quickly over time, so that their modulations can be perceived easily. 3 types of fluctuations rhythms will be considered : 10 minutes, 1 minute and 1 second.
The combination of data will need to be relevant so that, together, they indeed make people feel the rhythm of a place and of the several streams crossing it.
Specific working periods with William Guicquero, researcher in CEA-Léti, and other researchers / ingeeneers involved in the project FESTIVAL will focus on identifying data which are relevant in terms of dynamic and content for the artwork. This selection will also be done in discussion with locations presenting the installation.

3-2- Data generated by audience watching the artistic installation

A video camera capture spectators and generate in real time two types of data : spectators’ silhouettes and a photo portrait of one of the spectators chosen randomly.
For image capture and processing, the artist decided to use a « smart cam », a platform developed by CEA-Léti in the framework of FESTIVAL to do local smart vision through live image processing. The system enables endless reconfigurations. It enables, for example, to remove a picture’s background, keep only people’s silhouettes and replace them in another picture, count the number of people being captured, track their movements… That type of platform will enable Lionel Palun to extract the audience body and face from their original environment and place them into an abstract environment, just next to somebody from another place in the world.
Several research residencies with William Guicquero, researcher at CEA-Léti enabled Lionel Palun to explore the potential open by this camera and to develop the specific applications required for the artistic installation.

Spectators’ silhouettes are inlayed in real time in the graphical score

Photo portraits

Photo portraits are captured by the video camera and get overlayed on the graphical score and transformed right away into monochromatic particles.
The spectator from which the face has been captured can move the system of particles thanks to its body movement during about 10 seconds. The portrait then get erased from the device and another portrait takes its place.

The portrait is transformed in a system of particle and disappear right away into the video feedback.

4 - Complete schema of the artistic installation’s device

The schema hereafter represents the artistic installation’s device. In this final device, the installation screen differs from the screen where the feedback is being created. The platform is a computer which receives data from video camera and sensors, creates real time graphical score, overlay it with video feedback stream and send back this stream on the screens in both locations.

5. Technical requirements for the presentation of the installation

The installation requires in both locations :
- a giant TV HD screen (at least 3x4 metres)
- a dedicated high speed & symetrical network (same speed for inputs and outputs) with possibility to keep the same IP address.
- access to local data
- possibility to secure the artist’s material (camera and computer).

All the other material is being brought by the artist / Atelier Arts Sciences (computers, cameras,
artwork’s cartel)


Electro-video artist
born in 1972
This artist explores the connection between the screen image and the performing arts, where conceptually, this medium plays an equivalent role in the show as dance, text, sound or lighting do.
With a background in Physics - degree in engineering (Physics), PhD in nanotechnology, assistant professor in electronics in Grenoble – he has engaged in live shows since 2001, working with the digital image in many different contexts.
He has conceived more than twenty artistic installations and worked in about thirty different performances with many artists in the fields of dance, theater, music, light and cinema (Jérôme Noetinger, Will Guthrie, Riojim, Christophe Cardoen, Delphine Dolce, Dominique Lentin, Camel Zekri, Yann Lheureux,
Frédéric Tentelier, Broadway, Pascal Mengelle, Cédric Marchal, Anne-Marie Pascoli, etc.).

1. The producer
Atelier Arts Sciences
“Atelier Arts Sciences” is an innovation platform at the crossroads of artistic
worlds, scientific, technological and industrial organizing cross search
homes for everyone to find footbridges, establish common territories and
nourish each other.
In this framework were born many shows, exhibitions and devices that are
broadcast in France and worldwide. Among these include “Virus // Antivirus”
of Annabelle Bonnery, Cinématique and XYZT, Les paysages abstraits
of Adrien Mondot, Aucun home n’est une île of Fabrice Melquiot and
Roland Auzet, Les Mécaniques Poétiques of Ez3kiel, The Terza Luce of
Michele Tadini, The Bionic Orchestra 2.0 with Cie Organic Orchestra, etc.
These residences have allowed the emergence of new ideas, integration
of new technologies in live performance while boosting the creativity of
researchers, bringing breakthrough innovations in scientific and industrial
fields - particularly through the development of innovative uses of new
Since 2011, it also organizes EXPERIMENTA, the Fair, an arts, sciences and
technology fair that welcomed 6 000 people in 2016.
Atelier Arts Sciences is not a juridical structure but a cooperation agreement between Hexagone Scène Nationale Arts Sciences and CEA-Grenoble. Atelier Arts Sciences is administratively managed by Hexagone Scène Nationale Arts Sciences which is thus co-producer of this project.

2. Financial support
The research project benefits, in the framework of FESTIVAL, from financial support from the Horizon 2020 Program of the European Commission (agreement 643275) and from the Japanese National Institute of Information and Communications.
Fresque#1 also benefits from Fonds [SCAN] of Région Auvergne Rhône-Alpes and was welcomed in residency in TUBA (Lyon) and in Lieu Multiple (Poitiers).
