Partners since the creation of the biennial event, the Hexagone Scène Nationale Arts Sciences - Meylan and the CCSTI Grenoble - La Casemate presented, as part of the Rencontres-i 2009, a production of the Arts Sciences Workshop: Les Mécaniques poétiques. These interactive installations were created by Yann Nguema of the EZ3kiel group, engineers and researchers from CEA - Leti Grenoble and engineers from Erasme, the Rhône multimedia centr

Between poetry and technology...
With an aesthetic that evokes the industrial revolution and awakens the melancholy of our collective memory, Les Mécaniques poétiques condense the past and new technologies in an anachronistic way.
These installations are the fruit of the crossroads of multiple disciplines and draw their strength from both the artistic research of an independent music group and the technology-oriented research of the CEA - Grenoble laboratories. A mix that defies borders, and an exceptional opportunity to develop new access to the group's universe.

A network of complementary scientific partners: L'Atelier Arts Sciences, ERASME, MOVEA, Le CCSTI

All these partners have enabled EZ3kiel to create the eleven interactive modules that will make up Les Mécaniques poétiques. Their contribution will make it possible to improve certain wireless transmission techniques, to divert the use of RFID (Radio Frequency IDentification) chips, to recycle certain energies for the benefit of these poetic and technological installations.

THE INSTALLATIONS


THE MUSICAL CAGE
Sound and video installation.
An old cage whose bars play sounds like a harp when touched. The use of the video has yet to be determined (projections on objects -> stuffed birds, origami?), automaton, or none...
Hardware: Recover the contact points of the fingers on each of the bars. (minimum 3 octaves - 36 bars up to 50 if possible).

THE THEREMIN MADONNA
Sound and video installation.
A statue (madonna or virgin) placed in its alcove sings (like a musical saw, ondes martinot) according to the position of the spectator's hand. Like a theremin, the movements of the hand in front of the Madonna directly influence the pitch and modulation of the sound. Projections on the statue or the alcove (to be defined - tears, clothes, ornaments...) accompany and support her singing.

LE PIANO
Installation sonore et vidéo. Ce projet repose en partie sur son esthétique. Le piano est un instrument qui s’intègre parfaitement à l’ univers développé sur le DVDrom Naphtaline. Le piano sera coupé verticalement au quart (2 ou 3 octaves coté aigu) en épargnant la mécanique des touches. L’objet final serait donc un piano réduit mais fonctionnel au niveau mécanique. Il est envisagé de mettre un écran plat en lieu et place de la partition.

THE STELESCOPE
Video installation.
On its tripod (azimuthal mount) an old telescope (wood, brass) with a diameter of the end of the lens large enough to accommodate a small LCD screen (8-10 inches) allows by its orientation to see in its sight a landscape. Like a Quicktime VR, the rotation of the lens also causes the rotation of the landscape. The idea is to recreate a virtual panoramic environment in which the viewer can choose his or her axis of observation and aperture (zoom) by manipulating the telescope and its focus wheel respectively. A monitor, or an external screen can broadcast the calculated image to allow other passive spectators to understand the logic of the installation.

THE FLASKS
Sound and light installation composed of 12, 24 or 36 (depending on the number of octave chosen) transparent glass jars with their lids (bombonnière type, or pharmacy bottle) arranged in order of size like the "tubes" of a church organ. As soon as a lid is lifted, a sound (verrophone type) is heard, giving the impression that it is of the transparent jar. It stops when the lid is put back on. The note emitted is tuned according to the chromatic scale of each jar. The sound activity of each jar can be emphasised by a respective lighting system.

THE CYCLOHARP
Animation created on the basis of an old sewing machine rehabilitated into a real digital music box. Installed as if on a piano, the protagonist generates buttons, rhythms and melodies from the sound universe of the album Naphtaline, as he manipulates the pedal board and the various functions.

THE LOST BALLS...
Where the manipulation of a curious barometer controls the rotations of a virtual stage covered with balls and sound obstacles. The melodies are born from the shocks produced by the physical movement of the balls, and the starting up of a disc.
The intriguing effect is in the manipulation of this wireless object which reacts in real time to the inclination given to it.

THE CORDS
Grattez les cordes du piano graphique, faites bouger celles ci sur la table-écran à l’aide des boutons cuivrés, laissez vous aller sur cette écran tactile à orchestrer les mélodies de cet instrument hors norme.

THE GARDENS OF EXEBECCE
A bike ride through 4 virtual and phantasmagorical universes.
The two-way pedaling allows you to move forward or backward in desert, lunar or green meadows landscapes... while the brake handles offer the possibility of integrating or making objects disappear, such as windmills, coastal lighthouses, flying machines... Each object is associated with a sound, the multiple combinations of which modulate the melodies according to the pedaling and the brake strokes. The sound of the bell allows you to change worlds in the blink of an eye.

WORKSHOP
An "electro waves" workshop for young people...
Without revealing the technical secrets of the poetic mechanics of EZ3kiel, the mediation team of the CCSTI Grenoble proposes in parallel, to young people from 7 years old, a discovery and an initiation to sound and electromagnetic manipulations. From Chaldni's plates to electronic Fireflies, the universe of sound and electromagnetic waves is open to all.

Designed to be itinerant, these interactive installations complete the musical and visual universe of Ez3kiel.
This interactive installation was presented for the first time during the Arts-Sciences Biennial, Rencontres-i 2009, at the Centre de Culture Scientifique Technique et Industrielle in Grenoble from 2 October to 20 December 2009.
