(2017) Data driven kinetic sculpture.
Wood, Raspberry Pi, screen, Arduino, motor & custom software.

“Cyma” (from Greek: κῦμα, meaning “wave”) is a real time data driven kinetic sculpture highly inspired by natural repeatability and wave movement. An array of wood planks, connected only with a nylon thread passed from the center, is hanged from the ceiling and reaches the floor. The bottom plank is rotating periodically and sets the whole sculpture in motion. The motion of the bottom plank is creating a wave that physically spreads from one wood to the other. Real time data of the solar wind are defining the motion of the wave. The whole sculpture is waving without any mechanical force (except from the bottom plank), in the natural fundamental frequency and in higher modes called harmonics in a hypnotic and mesmerizing way.

The movement of the sculpture is driven in real time by live data of the solar wind. The strength of the wave movement (amplitude of the modulation) is controlled by the solar wind speed and the mode of waves (fundamental or harmonics) is controlled by north-south direction of the interplanetary magnetic field (Bz). A screen placed near the sculpture, projects the data and movement visualization.

About the Data

The Deep Space Climate Observatory (DSCOVR) mission is now the primary source for real-time solar wind and interplanetary magnetic field data but there is one more satellite at the Sun-Earth L1 point that measures the incoming solar wind and and that is the Advanced Composition Explorer. This satellite used to be the primary real-time space weather data source up until July 2016 when DSCOVR become fully operational.

The Solar Wind

The solar wind is a stream of charged particles (a plasma) released from the Sun. This stream constantly varies in speed, density and temperature. The most dramatic difference in these three parameters occur when the solar wind escapes from a coronal hole or as a coronal mass ejection. When these solar wind structures arrive at Earth they encounter Earth’s magnetic field where solar wind particles are able to enter our atmosphere around our planet’s magnetic north and south pole. The solar wind particles collide there with the atoms that make up our atmosphere like nitrogen and oxygen atoms which in turn gives them energy which they slowly release as light. The speed of the solar wind is an important factor. Particles with a higher speed hit Earth’s magnetosphere harder and have a higher chance of causing disturbed geomagnetic conditions as they compress the magnetosphere. (

The Interplanetary Magnetic Field (IMF)

The interplanetary magnetic field (IMF) plays a huge rule in how the solar wind interacts with Earth’s magnetosphere. In this article we will learn what the interplanetary magnetic field is and how it affects auroral activity here on Earth.

The Sun’s magnetic field

During solar minimum, the magnetic field of the Sun looks similar to Earth’s magnetic field. It looks a bit like an ordinary bar magnet with closed lines close to the equator and open field lines near the poles. Scientist call those areas a dipole. The dipole field of the Sun is about as strong as a magnet on a refrigerator (around 50 gauss). The magnetic field of the Earth is about 100 times weaker.

Around solar maximum, when the sun reaches her maximum activity, many sunspots are visible on the visible solar disk. These sunspots are filled with magnetism and large magnetic field lines which run material along them. These field lines are often hundreds of times stronger than the surrounding dipole. This causes the magnetic field around the Sun to be a very complex magnetic field with many disturbed field lines.

The magnetic field of our Sun doesn’t stay around the Sun itself. The solar wind carries it through the Solar System until it reaches the heliopause. The heliopause is the place where the solar wind comes to a stop and where it collides with the interstellar medium. Because the Sun turns around her axis (once in about 25 days) the interplanetary magnetic field has a spiral shape which is called the Parker Spiral.

Bt value

The Bt value of the interplanetary magnetic field indicates the total strength of the interplanetary magnetic field. The higher this value, the better it is for enhanced geomagnetic conditions. Moderate Interplanetary Magnetic Field strength values start at 15nT but for middle latitude locations, values of 25nT or more are desirable.


The Aurora

Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere, where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity (

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.

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 (?)

«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
  • Τα παιδιά που παίζουν

«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 relationship between colors and sound frequencies. The famous painting of Raffaello “Madonna del Prato” (Madonna of the Meadow) is decomposed into 10,000 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.


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.
