DELTΔ (Echolyse series)

Site-specific Installation

EN

DELTΔ, the fourth letter of the Greek alphabet, has been represented since antiquity by an upward-pointing triangle. Originating from the corresponding letter in the Phoenician alphabet, it derives from a hieroglyph depicting a doorway.

Based on the technique of anamorphosis, DELTΔ comes into conflict with the exhibition space by projecting the simulation of a virtual environment. The work unfolds in multiple forms and projections, always positioned in the corners of the room.

It generates visual tension between the anamorphic form and the light which, reflecting irregularly onto the adjacent walls, disrupts the perception of the architecture and alters its reading.

The viewer is invited to move through the space to reach the precise anamorphic vantage point, where a moving tunnel emerges from the gravity point of the projected form.

Conceived as a loop unfolding in both space and time, DELTΔ is accompanied by a sound design by Thomas Vaquié, based on the Shepard tone, simulating an infinite ascent.

DELTΔ, quatrième lettre de l’alphabet grec, est représentée depuis l’Antiquité par un triangle pointé vers le haut. Issue de la lettre correspondante de l’alphabet phénicien, elle trouve son origine dans un hiéroglyphe figurant une porte.

Basée sur la technique de l’anamorphose, DELTΔ entre en conflit avec l’espace d’exposition en y projetant la simulation d’un espace virtuel. L’œuvre se déploie sous plusieurs formes et projections, toujours localisées dans les angles de la salle.

Elle crée une tension visuelle entre la forme anamorphosée et la lumière qui, en se réfléchissant de manière irrégulière sur les murs adjacents, perturbe la perception de l’architecture et en modifie la lecture.

Le spectateur est invité à traverser l’espace pour atteindre le point précis d’anamorphose, où se révèle un tunnel en mouvement émergeant du point de gravité de la forme projetée.

Pensée comme une boucle qui se déploie à la fois dans l’espace et dans le temps, DELTΔ est accompagnée d’un design sonore de Thomas Vaquié, fondé sur la gamme de Shepard, simulant une montée infinie.
