Fresque #1

Presentation of the artwork

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.

Technical Description

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 3×4 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)

  • Lionel Palun

    Video artist
    Born in 1972 in Marseille, France.

    Lionel pursued a university education as a physician, qualifying as an engineer at the ENSPG (physics) and obtaining a phd from the UJF (in nano electronics). He worked for 2 years as a teacher and researcher in Grenoble at the LPSC (electronics). Following an encounter with contemporary dance, in particular with the work of the Pascoli company, he branched out into a singular research on the relationship between images and the stage, aiming to make this media an actor in its own right in the performing arts, on a par with dance, texts, sound and lighting.
    Lionel Palun is a co-founder of the Association 720 Digital, a member of Collégiale du 102, a member of the editorial committee of the quarterly magazine Revue & Corrigée and was on the board of directors of CitéDanse for 5 years.
    Since September 2017, Lionel Palun has been an associate artist at the Hexagone Scène Nationale Arts-Sciences de Meylan as part of a three-year residency funded by the Conseil Départemental de l’Isère.

    Duo and Improvisation:
    The core of his present research is a series of duos (generally improvised) that explore possible relationships between images and the other performing arts (Image/Dance, Image/Theatre, Image/Music, Image/Lighting, Video/Film…). The lightness of the duo makes it possible to combine the demands of a refined research with regular encounters with the public. These studies have enabled him to work with artists as diverse as Jérôme Noetinger, Will Guthrie, Riojim, Christophe Cardoen, Delphine Dolce and Dominique Lentin. That is where the alchemy that sustains his work developed.
    Art installations:
    Lionel Palun is regularly invited to present video and sound installations: Condition Publique in Roubaix, Nuit Blanche in Metz, Collectif Brouhaha…
    Video performance: Video performance is a tool for research and creative residencies in situ. It can either be a motor for starting the writing process or proposed as a singular form.
    Video creations:
    for dance and theatre pieces or concerts in collaboration with film directors, choreographers, musicians and collectives (Camel Zekri, Yann Lheureux, Frédéric Tentelier, Broadway, Pascal Mengelle, Cédric Marchal, Anne-Marie Pascoli,…) These video creations (written scores or improvisations) are an opportunity for artists to compare the written compositions of other artists.
    Sound creation: By physically diverting a video signal, he develops original digital tools in order to project the video signal into the speakers …
    Workshops and educational presentations:
    He regularly leads workshops for different audiences: Fine arts students, primary schools (Lumix project with Association Muzzix) and community centres. He also ran a course of mise en scene and an introduction to light images for Kaléidoscope, a project for the Opera de Lyon.
    Software design:
    Besides mastering the professional tools of digital imagery and multimedia, his university education and work led him to developing his own software programme, In Videre for creating and diffusing images. This programme is both a tool for video production and an original instrument for improvisation and video performances.
