ONION SKIN (Echolyse project)
A/V Installation

Onion Skin is a graphical work about the re-composition of time and space through a game of perspectives, both of the exhibition space itself and that of the projection canvas. Built around a progressive structure, made up of 4 parts lasting 14 minutes in total, the piece plays on the principle of repetition and scale to create a physical and hypnotic experience that opens doors onto the hidden and untouchable.
The music of Onion Skin is built around the 3 perspectives offered by the installation, which are front, left and right. Each of the three perspectives correspond to a series of notes.
The music was composed on the final editing of the video and each « peelings » sounds depending on its color, speed and number of repetitions.
The 5.1 surround sound set-up accentuates the physical dimension of the installation, strengthening and playing with the impression of volume and space.

Onion Skin est un travail sur la recomposition du temps et de l'espace à travers un jeu de perspective, à la fois de l'espace d'exposition lui-même et celui de la surface de projection. Onion Skin joue sur le principe de la répétition et de l’échelle pour créer une expérience physique et hypnotique ouvrant les portes sur l’invisible.
Les animations, des éléments géométriques simples appelés « pelure », sont structurées selon un scénario progressif, divisé en quatre parties, formant un ensemble de 14 minutes.
La musique d'Onion Skin est construite autour des trois perspectives offertes par l'installation, à savoir la perspective centrale anamorphosée, et celle de gauche et la droite à partir du module de l'installation. Chacune des trois perspectives correspond à une série de notes.
La musique a été composée lors du montage final de la vidéo et chaque "épluchure" sonne en fonction de sa couleur, de sa vitesse et du nombre de répétitions.
Le son surround 5.1 accentue la dimension physique de l'installation, renforçant et jouant avec l'impression de volume et d'espace.Un son surround 5.1 accentue la dimension physique de l’installation, renforçant l’impression de volume et d’espace.
