Displace is a performative environment which intermingles multiple sensory phenomena in order to heighten and transform our habitual modes of perception. Over a 22 minute period, groups of 6 visitors progress through a sequence of sensory-based environments. At first, these environments intermingle gustatory and haptic stimuli but gradually other sensations are introduced. The installation culminates by placing the visitors inside an intense, almost hallucinatory space in which flickering color, sound and tactile vibrations merge to the point of saturation.
Displace is one of series of experiments conducted within the context of a larger research project entitled “Mediations of Sensation” developed by Chris Salter, TeZ and anthropologist David Howes.

ANHARMONIUM is an immersive installation and performance, investigating the spatial awareness of subtle fluctuations that emerge from vibrational phenomena. The interference patterns within a sonically activated fluid illuminated by laser emissions forge an augmented meditative space, a psycho-physical observatory. In nature, modal phenomena occur as interactions between diverse oscillating systems, producing mutual perturbations and deviations from pseudo-linear behaviors imposed by gravitational and electromagnetic parameters. The interferential and resonant modes produced by intermingling forces reveal the immense morphological range of matter set into motion. Only a small bandwidth of this range falls within the sensorial envelope of ordinary perception...   download dossier

creative investigations on stroboscopic light, binaural beats and interference patterns

PV868 is an experimental creation and performance aimed at producing an audiovisual feed/stimulus which would allow a peculiar effect of moving visual patterns to emerge directly in the brain of the viewer. This stimulus is generated in real-time by a combination of flickering video, in the form of abstract lights and color gradients, coupled with synchronized synthetic sounds (binaural beats) diffused in a surround quadraphonic system. These elements are always recombined in different ways by means of ad-hoc created software, controlled by TeZ with a “touch” wi-fi remote device.

The Optofonica Capsule is a futuristic design/architectural object, featuring a mechanized structure whose parts form an autonomous immersive audiovisual environment. The shell-like shape of the capsule envelopes the body of the visitor to optimize the experience of Surround and Tactile Sound. Low frequencies are fed through a specially constructed floor, directly into the bone system of the human body, thereby converting the sound into hyper-perceivable vibration. The five panels of the Capsule's helmet are designed with specific (carbon-fiber + acoustic foam) material and transducers so to vibrate and reproduce the surround sound field without any use of traditional speakers. A flat screen is positioned to cover most of the visual field of the spectator to engage sight at a short distance and panoramic vision...   download dossier  

CF# is a series of procedural video compositions inspired by the 20th century abstract art movement "Colorfield". The software generates an ever-changing videopainting by compositing two layers of algorithmic color gradients and photo maps which react in real time to a dual-channel sound composition. One sound channel is translated as an horizontal scanning line; the amplitude of the sound determines the alpha transparency of the colored line, appearing like a glass transparent surface. The second sound channel's amplitude determines the horizontal composition, visualizing the sound wave onto a different photo map at every turn. CF# 1_2n was released as part of the COLORFIELD VARIATION exhibition and DVD release, curated by Richard Chartier.   LINE  

Generative Live Cinema (GLC#) is a concept and software conceived for non-linear live-cinema performances. It is based on the interaction and interference between sound, algorithmic animation and video. Animated vectorial layers react to sound and generate variable movements in dialogue with "concrete" video footage. The combinations between the elements are controlled by the performers but unfold unpredictably, hence creating dynamic variations at each moment. The musician(s) and the video artist both influence and operate the system, as such establishing an exchange that transcends the usual improvisation practices.

Inspired by the philosophical elements underlying japanese traditional martial arts, Ai is the first of a trilogy (Ai-Ki-Do) of procedural video compositions. The photo and video material, taken by TeZ during a two weeks residency in Tokyo in 2004, is constantly recombined and mixed with newly created imagery and algorithmic vector animations. A process of masking also takes place, as such creating an interplay of dynamic shapes through which the video fragments are revealed. The installation unfolds over two screens, one more dynamic and cinematic, the other more static and meditative, reminiscent of a painting. The piece is complemented by an ever-changing soundtrack resulting as a layered mix of several ad-hoc created short compositions. This work investigates the possibility of rethinking video and cinema as a more organic blend of elements for non-linear storytelling and sensual ambience.

Protoquadro is an artistic technique conceived to use digital displays to produce objects that stand in a space as paintings used to do. These artworks have some characters of a traditional painting and some of a totally new class of objects, therefore the name, formed by the greek term "protos" (first) and the italian "quadro" (painting).
Ideated by Maurizio Martinucci and Federico Bonelli, Proquadro is a model for automated compositions starting from original and thematic photographic source material which is re-composed by means of specific algorithms into an animated and ever-changing painting. The Protoquadro generative compositions slowly unfold in the digital canvas and evolve in an organic fashion. They rely on distinct methods and techniques which render an intricate and fine-textured composition to reflect both the intuition and sensibility of the artist and the procedural models based on the simulation of natural laws and chaotic behaviors.
Current developments of Protoquadro are lead in collaboration with PHILIPS ExperienceLab, and artists Amy Jackson and Robert Fischer.
