Echolyse project


he Echolyse  is an ensemble of works that deal with the perception of space. Using various devices, geometric structures are projected into different architectural sites with the aim of simulating immaterial three-dimensional spaces. Depending on the project, the resulting immaterial space can provide a virtual extension or a means of perturbing the existing space. 

 

The projected structures come to life, decomposing and breaking into fragments over time.

Linear and repetitive, they are known as “Peelings,” a reference to the outer layers of certain vegetables. Hidden behind the first exterior membrane, the infinite number of layers reflects the idea that behind the visible, real world are other hidden aspects, imperceptible at first glance.

 

In order to uncover these aspects, the production of the works in the Echolyse project draws on a technique of image distortion that originated from research into perspective first carried out by artists in Renaissance Italy: Anamorphosis. 

 

From one chosen viewpoint, generally placed centrally and at eye-level, the “Peelings” detach themselves from their backdrop in order to create an optical illusion. This means that the viewer has to move around the space in order to see the work appear.

 

The fictitious viewpoint of the artist thus superimposes itself onto that of the viewer, cleverly pushing him or her to become a pedestal for the work, without which it couldn’t exist. The surprise effect of anamorphosis tests the viewer’s ability to deconstruct/reconstruct what he or she sees in order to better ask: “What do you really see? Does it match with what you think you see?”

 

This idea was implemented in different forms and formats: Onion Skin, DELTΔ, RCTNGL and Pêle-Mêle are the works, which show the project.

 

Onion Skin

Portfolio : Onion Skin

he  first  stage  in  the  Echolyse  project,  which  will  also  give  birth  to  other  works,  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. Onion Skin is augmented by a 5.1 sound broadcast that reinforces this impression of volume and space.

DELTΔ

ince ancient times, DELTΔ, the fourth letter of the Greek alphabet, has been represented by a triangle pointing upwards. Originating from the equivalent letter of the Phoenician alphabet, it is based on a hieroglyph initially representing a door.

 

Delta, the second stage in the Echolyse project, is a site specific installation, that explores, through a dematerialised door, the possibility of a fictional three-dimensional space.

 

Making use of the anamorphosis technique, the piece is based on the position of the spectator,  predetermined by the artist, from which the audience will be able to visually reconstitute the geometrical symbol and discover the “pelures” (peelings) emitting from the very center of its gravity.

he audiovisual generative installation Pêle-Mêle uses a double anamorphosis visible from one sole and unique viewpoint. Upon entering the room, the viewer finds himself at equal distance between two transparent modules in the form of right angles, situated on either side of the space, which superimpose themselves on the existing environment.

Geometric content made up of vertical and horizontal lines known as “Peelings” are projected and diffused from one module to the other.

The illusion of depth generates a similar effect to “wormholes,” evoking the possibility of the existence of space-time tunnels, which could be seen as a reference to quantum physics.

Viewers are free to move around within the structure and to choose their own viewpoint, wherever they are within the space.
