Slide Slide 1/x
slices of a light cone

Experimenting with and experiencing the simple Multiplicative Inverse function 1/x that reveals a tricky time causality. The events that appear first are generated by causes that happened after the causes of the events that appear after. Hyperbola: a slice of a double cone. A slice of a light cone. Time. Hyperbola: a path followed by the shadow of the tip of the sundial. Hyperbola : asymptotic coordinations - subatomic scattering trajectories - planetary escape velocities - gravity assisted swings. A swing in time. A fraction. A flash of light. A single event.
Slide “1/x” is a sound and light art-science installation based on the singularity character of the 1/x function. A system of weighted reciprocal functions generates light flashes and sonic events, while establishes a second singularity point that reverses the system's causality time space. Around the singular points of those functions, an intensive experience is created and the visitor immerse himself into a dramatic environment developed through micro and macro time scales of sound and light.

01101110: An Audiovisual Installation Based on the Cellular Automaton Rule 110
at SMC2020.Torino - the 17th Sound Music Computing Conference
Slide 01101110 is light-music installation echoing and celebrating the simplest mathematical model of computation. A series of light/shadow paintings depict instances of the evolution of Rule 110 one-dimensional cellular automaton (Rule 01101110 in binary) accompanied by a music layer based on the same process. The paintings are created by digitally fabricated perforated panels and white light LED beams; the panels diffract the light and project it on blank canvases hanged on the wall of the exhibition space. Each painting offers it's one unique light and sonic space. The automaton Rule 110 is the simplest known Turing complete system and therefore it is capable of simulating any computer algorithm. This piece offers an immersive experience of this remarkable property and reflects on the duality of complexity/simplicity. Slide Slide title: 01101110

Slide Slide Waiting for Response is part of the light and sound installation res·o·nant created by Mischa Kuball for the Jewish Museum Berlin. “As an important element of the installation, several loudspeakers, distributed through the room loop a series of 60-second-long sound clips - so called Skits - which were composed specially for res·o·nant by more than 50 musicians. Slide Waiting for Response is a sound clip - Skit - which interacts directly with the acoustics of the space revealing and being revealed.
8 impulses were designed and placed on a timeline according to geometrical transformations created by the artists.

Three haptic devices each containing two haptic faders are mutually coupled between them using virtual linear springs and dampers. During the composition, the performers feel each other’s gestures and collaboratively process the music material. The physical modelling parameters of the interaction are modified during the five sections of the composition. Slide A time-stretching algorithm, developed specifically to simultaneously process three stereo channels, is stretching in an out-of-sync- three copies of the same music clip. The performers are playing with the stretching algorithm and an amplitude modulation effect which are both mapped to the haptic physical model and are applied to recognisable classical and contemporary music compositions. Each of them is substantially time stretching the same music clip and simultaneously affects subtly or often abruptly the gestural behaviour of the other performers. Slide At various points in the composition, the music becomes gradually in sync and the performers realign their gestures. This phasing “game” between gestures and sound, creates tension and emphasises the physicality of the performance. The modelling coefficients often take values impossible to occur in nature such as negative damping between the interaction of the performers, thus creating very unfamiliar interaction sensation. Moreover, instabilities that occur due to the long feedback control delays makes the gestural and sonic dialogue very difficult and quite often unpredictable.

Slide Slide A MIDI processing device has been implemented for the Arduino UNO board, in order to control and program the lights of The Black Cheetahs concerts directly from the drum machine of the musicians. This implementation automates the stage lighting, previously performed live on stage by Odysseas Klissouras. The device made its debut at the Black cheetahs concert at Ableton Live 10 Release Party - Berlin - March 2018, since then the device is used in all their concerts. Slide title: midi lights

Slide Slide Slide Metronom, which stands for metronome in Welsh, is a live audiovisual composition for a custom designed haptic interface. The interface consist of four haptic faders, and a digitally fabricated transparent acrylic structure, etched and cut according to the requirements of the music and the visual content. The performer interacts hapticaly with the moving faders, which behave like metronomes, at various tempi and rhythmic motifs. The faders' mechanical sounds are recorded and processed in real-time by digital signal processing algorithms and projected sonically back into space. Moreover the positions of the faders, driven by automated procedures and altered mechanically by the performer gestures, are controlling various compositional parameters affecting the timbre, the rhythm and the movement of various projected words and phrases. Slide A gradual interplay between the shadows of the physical interface's structure, the human gestures and the light refraction from the acrylic surfaces shapes equally the visual elements of the composition. The present inter-media performance, is an interactive audio-visual composition and a dance between the hands of the performer and the movements of the haptic interface. Slide title: metronom

Slide Slide Slide Talandon, is a live composition for a custom designed electroacoustic musical instrument and light. The music is developed around a basic rhythmic pattern radiated directly from the body of the instrument and from a set of physical models simulating various vibrating structures. The interplay between the rhythmic gestures [form] of the performer and the resonance of the physical and virtual bodies [colour] is enriched, transformed and amplified by the presence of the light component of the composition. The novelty and the significance of the piece can be identified in the interaction and also in the interplay between the physical and the simulated sounds. Moreover the body of the instrument has been designed and developed using digital fabrication methods that reflect the rhythmical elements of the structure composition. Therefore the rhythmical patterns appear on the physical form, on the triggered light pulses and on the sonic component of the piece. Slide title: talandon
