(2006 – 2008)

Quantum blue (also known as X-lam) is a sophisticated apparatus, created by Tadej Komavec for Teo Spiller’s artistic projects.



Quantum Blue is a digital technology to enter peoples minds. Like with Schroedinger’s cat, it is at the same time in the state of showing and not showing the image. It all depends of the way observer looks at it.

Image doesn’t appear on retina. Watching is a subconscious process of several dedicated neural networks in our brain, each specialized for one partial task of analyzing light, entering our eyes.

The nerves in our eyes are in a very specific way sensitive to sights with unnaturally strong contrasts. The lightest parts are memorized as light shapes still after we close our eyes. Quantum blue uses this physiological phenomena to create images inside our mind, which don’t exist in any form in the physical world.


In Memoriam Igor Zabel

Just before opening of his exhibition 95-05 in the Museum of Modern Art, curator Igor Zabel died because of unexpected post-surgical complications. Quantum blue gave the audience an opportunity to be for a moment in their minds joined with Igor again. I is surprising how detailed image we get if we invert the that Quantum blue video.

Bending Einsteins’s Time-Space into a Quantum Texture

Spacial dimensions are often an issue in visual arts. In case of Quantum blue this is very complicated. The thin line is one dimensional in the context of Newtons physics. The observer ads the dimension of time (the fourth dimension of Einsteins time-space) as he moves his gaze over Quantum blue. One spatial dimension plus time create a two dimensional image in observers mind. A two dimensional image is usually at a measurable distance away from observer (the third spacial dimension). But a Quantum blue image is inside the observer, which we could define as a negative dimension. And there is, of course, the paradox of the quantum uncertainty principle, where until someone observes it, there is at the same time an image and no image.

A Pseudo Woodoo ritual

Quantum blue perfect fits a rave party. Intense rhythms, blinking lights and the waving mass create a magic attitude, inviting a techno-sorcery like Quantum blue to join the ritual. Dancers, swinging left-right their heads, are the ultimate Quantum blue users.

Inside the Web Server

How would it feel to be an electron moving inside the Internet infrastructure?

User enters a dark room. In every corner is one Quantum blue, between them are loudspeakers. Whenever a file is requested from author’s web server, a synthetic voice tells its name and the nearest Quantum blue shows it’s image. As user follows the voices, coming from different directions, he moves his gaze over Quantum blue and the image of the file from the web server for a moment levitates somewhere in his mind. The content of the Internet directly enters his mind.

Alphabet City Topography

Combining technology with dance is a big challenge. The strings of digits are very different from the smoothness of a moving human body. Letters are similar to digits, transferring meaning only when in strings. In the performance about the 19th century “alphabet war” two dancers played with a suspended Quantum blue, which was showing letters from different alphabets.

The Ghost of Tutankhamun

Making selfie with a famous landmark and than hurry to the next one is the way we perceive culture and history today. Swift, unreal, without depth.

Wanna make a selfie with Tutankhamun’s mask? You can’t, because Quantum blue enables only one: either you or the landmark. To catch the landmark, you must move the camera and your face is blurred. If you catch you face, Quantum blue shows a vertical light line instead of the image. In spite of that, there was a terrible crush around the room with Quantum blue in Cairo.

* Quantum blue was in 2006 also exhibited on Device.art in Zagreb, Belgrade and San Francisco, where four devices presented four different sacred texts. Presenting texts with Quantum blue is a very special experience, because we know there are texts, but are unable to read them.

** in 2010 Quantum blue was exhibited in Contemporary Arts Museum Celje.
