    Particle synthesis is an installation based on an autonomous, self-standing, audio-visual setting. Consequently the core of the work focuses on programmed, generative, processes within sound creation and music composition as to visualize, notate, these processes in real-time. The installation title 'particle synthesis' names the two principles constituting the work, the sonic technique of granular synthesis and the visual one of particles rendered in 3D real-time. Here every particle is a grain evolving in space and time. This inter-relation between sonic and spatial characteristics constitutes the main characteristics of the real-time rendering in 360 degree and the surround sound. The hexagonal shape of the installation translates these sonic and spatial specificities: six networked computers, each rendering 60 degrees of the 3d scene, are boxed in a transparent Plexiglas case also including a speaker. These boxes have the shape of a stage monitor and are placed next to each other on the ground to constitute the hexagonal ring. The design of the installation thus gives shape to the inherent spatial and sonic parameters of the software and exposes its constituting hardware as its specific form offers two perceptions and manifests the spectator's act of entering and listening; between soft and hardware; between perception and action.

      512 panneaux d'affichage de lettres à rouleaux, installés en cercle sur quatre niveaux, tournent et retournent… Sur le côté extérieur de l'installation, des bobines qui s'activent et se désactivent, enclenchant le mouvement des lettres… Le collectif bruxellois Lab(au) offre un ballet sonique de cliquetis mécanique étonnant et obsessionnel !

        Tessel is a kinetic sound installation investigating the perception of sound and space. The installation is constituted of a suspended and articulated topography of 4 x 2 m, subdivided into forty triangles. Twelve of them are fitted with motors and eight are equipped with audio transducers, thus creating a dynamic sonic space, evolving softly, constantly reconfigurated. The shape of the surface is transformed and synchronized with a musical composition, establishing a choreographic dialogue between sculpture and sound, while altering perception. Recalling Tinguely's poetic machines, Alexander Calder's mobiles or Buckminster Fuller's structures, Tessel is a sculpture that involves time and movement to continue the quest for a synesthetic perception of sonic and spatial phenomenons. The name ‘Tessel’ is derived from ‘tessellation’, a term applied to the geometric subdivision of a surface into plane polygons, also known as ‘tiling’. This technique is also used by 3D softwares to allow the calculation of rendered images. The term has its origin in the Latin word ‘tessella’, describing the square tiles used to make mosaics. Tessel is based on the ‘pinwheel pattern’, a non-periodic tiling coined by mathematicians Charles Radin and John Conway, which allows the creation of an infinitely complex geometry, only constructed from a single right triangle. Here, the pinwheel is transformed to meet the movement requirements, resulting in a new pattern composed of 4 different triangles, which is then folded and transposed to the third dimension. This peculiar geometric construction suggests that the work is only a part of a much wider whole, a finite element extracted from an infinite system. The sound composition and the movements are closely linked together : the speed and acceleration of each motors are used as datas to process and diffuse the sound in real-time. The geometrical properties of the triangles define the 4 different phases of the composition, while the structure inside each theme follows the dimensions and symmetries of each triangle type. Tessel is a collaboration between French composer and artist David Letellier, and LAb[au], Belgian electronic arts studio. Tessel is a co-production of the galleries MediaRuimte (Brussels) and Roger Tator (Lyon), realised with the financial support of Arcadi, Dicream and the Commission des Arts Numériques de la Communauté Française de Belgique.
