Interactive Light Installation. Optical fibres, LEDs, Raspberry Pi, sensors, custom software.

Immersive and meditational visual and audio space on the theme of ‘rebirth’

Using light and sound as the main elements for creating an immersive environment, this installation is trying to emulate a feeling of rebirth. More than one hundred luminous optical fibres form a pentagonal light cage that stands dimly lit, waiting for a visitor. When the visitor enters inside it, he/she ignites a light and sound sequence, a performance that will transform the light cage into a meditational visual and audio space, where the visitor is challenged to rebirth.

At the beginning, the light will be low powered and white and the sounds will be simple, distant and low frequency. Then more colours will start to appear, together with more complex patterns, rhythms and rich sound frequencies. The sound will be a mix of digital generated interpolated noise along with natural sounds recorded in an underwater environment in order to emulate the audioscape of the fetus. A final light and sound blast will mark the rebirth moment.

Touch Me


(2016) Interactive Sculpture. Optical fibers, leds, raspberry pi, arduino & custom software.

Please, touch me. Unlike other artworks that we are advised to keep distance, this sculpture invites you to touch it. With reference to the ancient cycladic idols, this black head is standing dark, like an extraterrestrial visitor, waiting for an encounter. In response, it will emit cold blue and violet light through hundred optical fibers that are fitted in its surface. At the same time a soundscape will be generated based on the movements of the hands that are touching the sculpture. As the visitor interacts and get connected with the artwork, a special algorithm is calculating the amount of engagement and transforms the lights to warmer red and orange colors.

“Touch me” is a metaphor on human and technology relationship. It is trying to explore the difficulties of human-machine interaction. A simple interaction like touch is sometimes very difficult to achieve. People may hesitate to touch the sculpture (especially in a gallery-exhibition environment). When they finally do it, some may feel uncomfortable by the sculpture reaction and other may feel attracted and charmed. After so many interactive devices that surround us in everyday life, how used are we in a human-machine interaction?

Dollhouse

Interactive installation. Cardboard boxes, projector, sensors, 8 speakers and custom software.

Dollhouse is an interactive installation consisting of boxes placed in a horizontal structure that resembles a dollhouse. Inside each box we can watch a “lodger” who lives in this space. Some “lodgers” of dollhouse want to protect their privacy while others seek promotion. What happens when you approach to watch better or to see if somebody lives there?

The work is a comment on the privacy and personal space. Personal space is not always one physical location like our home, but it can be a pavement, a trip by car or an everyday routine. Visitors have the opportunity to watch and listen to the lives in this dollhouse. Some of lodgers want to protect their privacy, they closed the windows, avoiding exposure and the publicity. Others seek publicity and do their best to attract our attention. Some of them are completely indifferent to our existence.
23 lodgers and 23 boxes. One for each of us.
What is personal space for each of us? How our space is affected by the fact that someone is watching us? Do I want to protect my privacy or am I seeking exposure? How this can become an obsession?
Do they see me (?)

  •      The dancers

«Δικό μου» a piece of space, Athens, Greece (March 16, 2016)

A teaser video of the exhibition «Δικό μου» a piece of space at Romantso, Athens, Greece (March 16, 2016)


Διαδραστική εγκατάσταση. Χαρτοκιβώτια, βιντεοπροβολέας, αισθητήρες, 8 ηχεία και ειδικό λογισμικό.

Το Dollhouse (κουκλόσπιτο) είναι μία διαδραστική εγκατάσταση που αποτελείται από χαρτοκιβώτια τοποθετημένα σε μία οριζόντια δομή που θυμίζει ένα κουκλόσπιτο. Μέσα σε κάθε κουτί μπορούμε να παρακολουθήσουμε και έναν «ένοικο» που ζει σε αυτόν το χώρο. Κάποιοι «ένοικοι» του κουκλόσπιτου θέλουν να προστατεύσουν την ιδιωτικότητά τους ενώ κάποιοι άλλοι επιζητούν την προβολή της. Τι γίνεται όταν πλησιάσουμε κοντά για να παρακολουθήσουμε καλύτερα ή για να διαπιστώσουμε αν μένει κάποιος εκεί;

Το έργο είναι ένα σχόλιο για την ιδιωτικότητα και τον προσωπικό χώρο. Ο προσωπικός χώρος που δεν είναι πάντα μία υπαρκτή σταθερή τοποθεσία όπως το σπίτι μας, αλλά μπορεί να είναι ένα πεζοδρόμιο, μία διαδρομή με το αυτοκίνητο ή μία καθημερινή συνήθεια. Ο επισκέπτης έχει την δυνατότητα να παρακολουθήσει και να ακούσει τις ζωές μέσα σε αυτό το κουκλόσπιτο. Κάποιοι από ενοίκους θέλοντας να προστατεύσουν την ιδιωτικότητά τους, μας κλείνουν τα παράθυρα αποφεύγοντας την έκθεση και τα αδιάκριτα μάτια. Άλλοι επιζητούν την προβολή και κάνουν τα πάντα για να τραβήξουν την προσοχή μας. Υπάρχουν και αυτοί που αδιαφορούν εντελώς για την ύπαρξή μας.

23 ένοικοι και 23 κουτιά. Ένα για τον καθένα μας.

Τι θεωρεί τελικά ο καθένας προσωπικό χώρο; Πόσο επηρεάζεται ο χώρος μας από το γεγονός ότι μας παρακολουθούν; Θέλω να προστατεύσω την ιδιωτικότητά μου ή επιζητώ την προβολή της; Πόσο η προβολή της μπορεί να γίνει εμμονή;

Με βλέπουν(;)

Οι ένοικοι:

  • Οι χορευτές
  • Η φωλιά των μερμηγκιών
  • Ο video blogger
  • Οι δρόμοι του San Francisco

«Δικό μου» a piece of space

Ποιος είναι ο χώρος μου; Οι διαστάσεις του; Πόσο δικός μου είναι τελικά; Ποιες είναι οι ιδιοκτησίες μου και ποια τα όρια μου; Πόσο ρευστά είναι αυτά τα όρια; Πόσο μου ανήκει το σπίτι μου; Μου ανήκουν οι καθημερινές μου διαδρομές; Ποιες είναι οι παράμετροι που διαμορφώνουν το χώρο μου; Ο χρόνος, εγώ, οι άλλοι. Όταν εκλείπουν τα απτά όρια πόσο ρευστός είναι ο προσωπικός χώρος;

Πως μπορεί η τέχνη σε συνδυασμό με την τεχνολογία να απεικονίσουν τη λεπτή ισορροπία αυτής της ρευστότητας; Τα έργα της έκθεσης, μελετώντας τις πτυχές που μεταβάλλουν τον προσωπικό μας χώρο στην πόλη, επιχειρούν να αποτυπώσουν και να ορίσουν τη σημασία του. Προσεγγίζουν τις κοινωνικές και χωρικές διεκδικήσεις, τις συνειδητές και ασυνείδητες κατακτήσεις του ατόμου μέσα στην πόλη.

Στο πλαίσιο του ΠΜΣ «Πολιτιστική Διαχείριση» του Παντείου Πανεπιστημίου, η Ραφαέλα Καραγιάννη και η Αναστασία Τερζίδου, συνδιοργανώνουν μια έκθεση ψηφιακών τεχνών που μελετά τη διάδραση μεταξύ δημιουργού-έργου-κοινού. Η έκθεση είναι μικρής κλίμακας και αποτελείται από πρωτότυπα έργα Ελλήνων καλλιτεχνών.

Ichographs MdelP

Audiovisual Installation. 1ch HD video| 2ch sound. Dimension Variable.
Ichographs MdelP (Madonna del Prato) is a sound and picture artwork that explores the relationships between colors and frequencies. The famous painting of Raffaello “Madonna del Prato” (Madonna of the Meadow) is decomposed into 10,0000 cubic particles each carrying a frequency relevant to its color (HSV hue value). As we move around, we hear the sound of all these colors/frequency generator particles fly in the space towards the canvas to compose the painting. Warm colors (like red) are higher frequencies and cold colors (like blue) are lower frequencies.

Ichographs is a method of creating soundscapes using visual stimulus and the color-frequency transformation. The painting is transformed into the audio domain and back to visual producing a contemporary amalgamation. As we pass through the various color/frequency layers, we investigate the connections between classical aesthetics and the digital practice, revealing a latent version of the old masterpiece. The final artwork is a contemporary amalgamation of the old painting and the modern abstraction methods, a harmonious dialog between the old and the new, the analog and the digital.

Technical Information

“Ichographs MdelP”was created using Open Frameworks and Pure Data. The image was divided into 10,000 pieces. Each piece was assigned a frequency depending on its color and more specifically its HSV hue value. Warm colors (like red) are higher frequencies (up to 800Hz) and cold colors (like blue) are lower frequencies (down to 50Hz). Other properties of the color like the saturation and the value (again in HSV color representation) are used for defining the dimensions, the position and the speed of the particle.

Color-Frequency-Relationship

Warm colors (like red) are higher frequencies (up to 800Hz) and cold colors (like blue) are lower frequencies (down to 50Hz)

As the camera moves around we hear the sound that all these 10,000 moving colors/frequency generators are producing. The loudness of each particle is proportional to the distance from viewer. As a result, when we pass over over Madonna’s scarlet dress, we hear the high “red” frequencies; conversely, as it scans fragments of the blue sky, we start hearing the low “blue” frequencies. All the sound data(sound amplitudes) were sent via OSC to a Pure Data  patch with a set of 600 sine-wave generators for producing the sound.

Pentavlos

Kinetic installation. Acrylic tubes, balls, LEDs, motors and custom software.

Pentavlos is a kinetic light and sound sculpture, where harmony and periodicity are the fundamental elements. Motion, sound and light, all are obeying the laws of the harmonic oscillation.

Five white balls are oscillating inside acrylic tubes using the thrust of small propellers at the bottom of each system. Both balls and the tubes are emitting a light pulse and sound tone in significant point of the movement. Each tube is “tuned” in a different note of a natural pentatonic scale. The periods of the oscillations are accurately adjusted to form visual traveling waves, standing waves and quasi chaos.
There are three chapters:

•   City Memories   •   City Machines   •   City Lights

Eco-Leaf

Pentavlos is using a simple mechanism to detect the presence of visitors around it. When there are no visitors, the installation enters a standby mode where it consumes minimum energy.

Pentavlos and Invisible Cities

Pentavlos was presented at Italian Cultural Institution at Athens during a two day even organized by Athens University dedicated to Italo Calvino and his work “Invisible Cities”.

The periodicity and the harmonic motion, which are the key elements of the installation Pentavlos, can also be found in the novel “Invisible Cities” by Calvino. The book is divided into 9 parts, with each part containing a different number of cities. Both the length of the title of each section and how they move from one thematic group to another, follow the rules of the harmonic (sinusoidal) motion. Calvino has also chosen to integrate the periodicity to the repeated structure and the continuous alternation between dialogue and descriptions of cities.

Invicible Cities diagram

Calvino places the cities in different thematic groups in a reciprocating way that resembles that of the oscillation.

The Theory Behind Pentavlos

Harmonic motion, a periodic movement between two points, occur widely in nature. A simple harmonic oscillator is used to model and explain many phenomena in both classical physics and quantum mechanics from modeling phonons to describing quantum fields. Beyond that, a vast amount of motions, sounds, and systems in general are analyzable as superposition of simple harmonic motions of varying frequencies and amplitudes (Fourier analysis).

If we chose five different harmonic oscillators with gradually different periods, they will start together and quickly will fall out of sync, because of their different periods of oscillation, and soon they start to form visual traveling waves, standing waves and quasi chaos.

Harmony and periodicity appears in many parts of the work with most important the harmonic oscillation of the balls. Additionally, the combining motion and the patterns that the five balls are producing along with way that the light fades in and out follows a sinusoidal form. The sound tones are simple sin waves that form a pentatonic scale, a scale that is consider as a very natural and harmonic.

The Sound of Pentavlos

In various significant points of the installation, for example when a ball passes from the middle of the motion path or when a tube is illuminated, the installation produces a tone. These tones are simple sinusoidal waves. All together they form a pentatonic scale with the following notes.

 

The 1st tube-ball system is playing an A3 and randomly the same note an octave higher and lower, hence A2 and A4. In the same manner the 2nd system is playing B2, B3, B4, the 3rd C#2, C#3,C#4, the 4th E2, E3, E4 and the 5th F#2, F#3, F#4.

A pentatonic scale consists of five overtones and is derived directly from the natural physical phenomenon of the harmonic series. To maximize this effect, Pentavlos is using the Pythagorean tuning and not the equal temperament notes. To form the scale we use the following formulas:

Pendulum 1st 2nd 3rd 4th 5th
Frequency Ratio 1 9/8 81/64 3/2 27/16
Note A B C# E F#
Frequency (Hz) Octave 2 110 123,8 139,2 165 185,6
Octave 3 220 247,5 278,4 330 371,25
Octave 4 440 495 556,8 660 742,5

Note: We are using the Pythagorean tuning and not the equal temperament notes.

The Technology of Pentavlos

The main parts of the installation are acrylic tubes, balls, leds and dc motors. Everything is controlled using an Arduino microcontroller. A custom android app installed on a phone is communicating via bluetooth with the Arduino and plays the sounds. The phone is also used to control various parameters of the installation (the power of the motors, the led luminosity e.c.t) .

Pentatono

Kinetic Installation. Optical fibres, LEDs, motors, arduino and custom software.

Pentatono is a kinetic light and sound sculpture, where harmony and periodicity are the fundamental elements. Motion, sound and light, all are obeying the laws of the harmonic oscillation.

Five acrylic balls are hanging from optical fibers and form five pendulums that are moving in the space using the thrust of small propellers. When a pendulum passes from the equilibrium position (the middle of the motion path) it emits a light pulse and sound tone. Each pendulum is “tuned” in a different note of a natural pentatonic scale. The lengths and hence the periods of the pendulums are accurately adjusted to form visual traveling waves, standing waves and quasi chaos.

The Theory Behind Pentatono

Harmonic motion, a periodic movement between two points, occur widely in nature. A simple harmonic oscillator is used to model and explain many phenomena in both classical physics and quantum mechanics from modelling phonons to describing quantum fields. Beyond that, a vast amount of motions, sounds, and systems in general are analyzable as superpositions of simple harmonic motions of varying frequencies and amplitudes (Fourier analysis).

While this underlying fundamental principle – the fourier series – is a purely abstract mathematical theorem, it is also responsible for our understanding of almost every aspect of the physical, biological and social world; including but not limited to acoustics, economics, quantum mechanics, predicting earthquakes, protein structures, DNA and the composition of distant stars and galaxies.Memo Akten about “Simple Harmonic Motion Series”

The pendulum is a simple harmonic oscillator. The period of a pendulum (T) depends on its length:   where L is the length of the pendulum and g is the local acceleration of gravity. We have chosen different lengths for the pendulums in order to have different periods. After we start all 5 pendulums together, they quickly fall out of sync, because of their different periods of oscillation, and soon they start to form visual traveling waves, standing waves and quasi chaos.

The installation is using the fundamental frequency (resonant frequency) of each pendulum in order to oscillate it. If T is the period of the pendulum, the motor is activated every T seconds for ½T of time.

Ηarmony and periodicity appears in many parts of the work like:

• The harmonic oscillation of the pendulums.
• The combining motion and the patterns that the five pendulums are producing.
• The sound tones are a simple sinusoidal tones.
• Various properties of light like maximum and minimum luminosity or fade out speed are following a sinusoidal form.
• The pentatonic scale is consider a very natural and harmonic scale. It consists of five overtones and is derived directly from the natural physical phenomenon of the harmonic series. To maximize this effect, Pentatono, is using the Pythagorean tuning and not the equal temperament notes.

Light Catcher

Installation. Optical fibres, LEDs, Raspberry Pi and custom software.

“Light Catcher” is a dialogue between sound and light. The installation is composed of numerous optical fibres that interact with sound. Sound is the driving force, light is generating the space. An electric spark is igniting the reaction. Light is entrapped inside the optical fibres, reacting only to sound stimulus. Acting like a catcher, the installation absorbs and emits light. This results an emergent dance of light from the fibres and the reflections on the surrounding surfaces. The white light dominates the installation but shades of other colors exist to highlight an audio event, like the sounding French horn playing a minor second interval. The visitor is invited to walk around the installation and explore the different visual and audio aspects.

The project was created using C++ for designing the light choreography. The sound was generated in Pure Data along with acoustic instruments that were mixed together. In the final installation, a Raspberry Pi hidden inside, is playing the audio and controlling the LEDs using Python.
