Onion Skin is an immersive installation by Olivier Ratsi,
Onion Skin is made up of a physical dimension – a module of two walls, positioned at right angles – augmented by a projection and a 5.1 sound broadcast.
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 whole experience of the installation is based on a very specific point of view. A precise position from which a new dimension is revealed to the audience by anamorphosis. 
The simple geometric elements (“peelings”) that seemed to be flat at first suddenly start delimiting a new space. 
The illusion of a new dimension within the installation slowly appears as the onion skins seem to be leaving their physical surface behind.

About The Music :

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.
