A/V installation, On Tour , 2012

Concept & visual design: Olivier Ratsi
Sound design: Thomas Vaquié
Producer: Nicolas Boritch - Antivj

Since ancient times, Delta, 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, an installation and part of the Echolyse project, is a work on the perception of space, 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.

About The Sound :

Based on Shepard tone effect, the sound of Delta works on the idea of an infinite dive in time.
