First some background:

The installation I’m working on these days is based on the idea of a division between the whole and the parts that constitutes said whole. A fascination with the theory of emergence, a term usually used about the novel and emergent behaviour seen in more or less complex systems based on relatively simple autonomous agents (examples are the way flocks of birds fly in formation, the way schools of fish move as one, or the way ant colonies organize with no central control), has given rise to the installation’s form.
The installation is built on a system of 16 autonomous agents, in the form of microcontroller controlled units each with an embedded LED (light), LDR (light sensor) and solenoid (for percussive sound). All the units are identical in shape and loaded with the same code. The units are spread throughout a space in all three dimensions, with a gap of approx. 1.5 meters between each other.

An analogy for the behaviour of the units is that they are like social creatures, feeling safe and content in the company of others like themselves. But when something/someone isolates them, they start to get agitated, wanting to get back into the fold. The units will regularly ping each other with light, and as long as they are touched by a beam of light within given intervals they are happy. The LED and LDR of each unit are placed at 90 degrees to each other, thereby making a rippling effect possible, as a unit can be separated from others on one side, but is still able to agitatedly blink it’s LED, transferring its “adrenalin” to the next unit in the group.

So, to take it from the beginning again:

I am currently thinking a lot about dual levels of behaviour, experience and interaction/reaction.
In the context of the above mentioned installation:

• Dual refers to the local versus the global, the individual unit versus the group, the active versus the passive interest shown by visitors.
• Behaviour refers to how the autonomous agents function by themselves, and how the installation functions when viewed as a whole.
• Experience refers to how people perceive the whole installation versus the parts that it is made of.
• Interaction/reaction refers to the kind of action people take when in the presence of the installation, whether they keep to the edges looking at, and listening to, the whole or diving into it playing around with the separate units.

My hope is that the installation will be perceived on both levels. First when someone enters the space it is in, they might stop up for a bit, viewing the play of light and shadows bouncing from unit to unit, listen to the soundscape. After a bit they might start getting interested in the separate units, trying to figure out how it works. The difficult part to predict is whether most people will dare start walking between the different units, discovering how they can be affected (or at least that they can be affected). I am looking forward to doing proper user tests to find out more about these things.
People are different. Some people shy away from everything that might put them in the spotlight, while others jump at every opportunity to explore new things. I hope that the installation will cater to both types of people, as visitors may choose themselves whether they want to interact or react, and whether the level of the behaviour in the installation that they experience is local, global or both. There are of course tricks one can use to force the timid visitor to interact in an installation such as this. One way is to create a sense of security by exhibiting in a smaller space, thus removing the audience/performer association from the experience. Another way is to place the first units a visitor will encounter right by the entrance to the space, forcing them to move through the installation to get inside. The trick is to hold on to the original idea of dual levels of experience; it must be possible to observe the installation from outside, while encouraging people to walk among the agents.

It’s not here. It is not missing. v2 from Kjetil Austvoll-Dahlgren on Vimeo.

“It’s not here. It is not missing.” is an interactive installation exploring the negative space of perceived reality, seeking to sensitize the visitor to the subtracted parts of the whole.
It uses the metaphor of shadows as masks for visuals as well as sound.

It cycles through two states, a subtractive state and an additive state, complementing each other as two approaches to the same theme: the small parts that make up the whole. The subtractive state is meditative and subtle, while the additive state is brash and immediate.

The installation is built with Arduino (arduino.cc/) and Processing (processing.org/). The music is by Sindre Husebø.

The basic setup:
10 LDR’s (light dependent resistors)
2 arduinos
2 projectors (minimum)
1 computer (with a graphics card capable of running multiple screens)
Space -> The installation utilizes the room it is in, every setup is unique.

I will attend a couple of performances tonight, more on those at a later point.



Now some thoughts and images from the different things I’ve experienced and observed so far:



Eleonora Oreggia (IT): “Virtual Entity”

Eleonora Oreggia has a background in archiving artistic and creative digital works. This always present difficulties when considering the multitudes of formats and versions often available of different works. She has now made a program for archiving these kinds of work, from a philosophical standpoint where she tries to isolate the different files and their states as “entities”. An example is giving files parent/child relations to each other, based on whether or not the have any “genetic” material in common. For instance, if I made a image collage of stills from a video work, the video would be the parent and the collage the child. In addition to different quantifiable data that she gives the different files, she also has the metadata slot where the qualitative description is written. This is of course subjective, and she refers to it as the “soul” of the digital entity. I find this view quite frascinating.



Exhibition Opening at Lydgalleriet:



“intrinsic” by Angie Atmadjaja was a beautiful installation. Four glowing tubes suspended from the ceiling in a dark room. They had small microphones attached them, and dimmed the light based on level of sound input. Ambient sound was running, and this together with the sounds from the visitors made the tubes come to life, almost dancing in their stillness.







“Health & Safety Violation #14 – Randomly Activated Tripwire Proposal” by Ben Woodeson was a cute interference in the hallway. The tripwire was hooked to an arduino, going up or down based on a random calculation between 1 and 30 seconds. But even if this was a random program, you could not help but feel that there was some sort of sensor involved. When I first walked over it it coincided with an upwards motion. I spent some time trying to find out exactly what it was I did so that I could controll it, but there you go. Standing there and observing other people interacting with it was a pure joy. Everything from people showing considerate care, to people getting a fright, to people not bothering a second look.







“Musica Vista 1.0″ by Carlos Tricas displayed some nice graphics based on the physical location of big foam buttons. A camera tracked the locations and visitors were encouraged to move the buttons around.







“Generative Audio Prototypes” by Dream Addictive, Carmen González and Leslie Garcia was a box that produced sound based on the nearness of things and people. IR sensors lined the sides and related to different parts of the soundscape, a knob adjusted the speed of the sounds created. Fun to play with.







“augen-auf-schlag” by Wolfgang Spahn and Thomas Gerwin was the most elaborate installation on display. An electronic drumkit was hooked up to liquid light projectors, the shapes, colours and orientations based on which drum pads you hit. Even more fun to play with.







“The serv seq” by Gijs Gieskes was a more transparent sound making machine, even though I didn’t find out exactly how to use before the artist came and explained. Optical sensors were attached to swinging arms, the sensors read the graphic pattern on a turntable, and the arms could be controlled to hit outside objects:  a cymbal, a wooden block and a plastic ball. You could control the speed of the turntable, the motion of the arms and a couple of other things I honestly can’t remember. Fun thing, but without instructions not really accessible.







New media/dance performance “Action Potential” by Jenny A Torino (US), Benjamin A Margolis (US) and Lee Azzarello (US)

This was, in my book, a classical example of falling in love with the technology without taking enough care to make sure the audience is happy/intrigued. Three “dancers” were rigged with a varying amount of sensors, boxes and cables. The sound was supposedly generated by the readings from the sensors, but if I hadn’t known I would rather think they moved to a prerecorded sound track with fancy props attached to themselves. After some time of moving around they started swapping sensors.



This was of course not really interesting to look at. The sensors were elaborately enough attached so that they used at least a couple of minutes doing it, standing there on stage, no music, no dancing, nothing of interest.



Audiovisual performance “Kunst Und Musik mit dem Tageslichtprojektor” by Ralf Schreiber (DE), Tina Tonagel (DE) and Christian Faubel (DE)







Now this was fantastic stuff. Three artist, three overhead projectors, loads of mechanical things making sounds. Basically, they made sounds with different things, dc motors that vibrated, strings and bow, blowing bubbles in water, etc. The sound was also amplified and modified, but it was in general quite easy to discern what made which sound. The neat trick was that they used the overhead projectors as tables, all the things that made sound were also carefully shaped and/or chosen based on how they would look projected onto the wall.







They went through several themes, both visually and musically.



And here’s the gear:



All in all a fantastic experience.



Noise jam “Noise Invaders” by Diego de Leon (ES)



Now this was just a plain old good noise performance. Enjoyed it immensely.
