light installation in the Fantoft-Paradis tunnel in Bergen, commissioned for the new metroline Bybanen which opened in end of june 2010.

The installation consists of two long wave patterns of light, one side red-white, the other blue-white. The total length is about 400m. The two wave patterns overlap, so for about 100 m you will see both the red and blue pulse. The material used is neon rope light.

Together with Marius Watz I was invited to make either a light or video work for one of the tunnels for the new Bybanen metroline in Bergen. You can see some images from Marius´ installation here.

I wanted to work with the fact that the train is moving at about 70km/h (about 20m/s) through the tunnel, using the movement of the train as a way of animating the two wave patterns mounted on the tunnel walls.

There were some interesting challenges to this project, as the installation was supposed to be ready for the opening of Bybanen in end of june. This meant I had to send in the proposal for the installation before the trains started to run. I ended up making an animation of some simple waveforms in Processing, which gave a pretty good impression of how this would be experienced when sitting in the train.

There are a lot of factors influencing how the work is experienced.  If you sit by the window closest to the tunnel wall the wave breaks up into rapidly changing curves and lines. If you sit closer to the middle of the tunnel you will see longer stretches of the wave. You will also see reflections of the waves in the windows of the train.

One thing I don´t have control over is the light inside the train, which is really bright. This dimishes the effect of the neon rope light washing the tunnel in different blends of blue, red and white (and potentially casting coloured shadows of the passengers onto the tunnel wall). Thus the installation exists in two different modes: The tunnel as a light modulator which can only be experienced when being inside the tunnel without any trains, or as animated wave pulses when riding the train through the tunnel.

Wind-up birds sound recordings

As mentioned in a previous post, Wind-up Birds made an appearance in the foresty hillside of Fløien. Fløiensvingene (The Fløien turns) is a curly path up the steep hill (as steep as 25 degrees), starting at about 180 m above sea level, and ending at about 300m.
It is a city forest, blending the sounds of the city with sounds of nature, as well as the sound of all the people using it.
I quickly edited together a few sound recordings from various points along the path to give you an impression of how the wind-up birds blended into their environment.

They´re back

For the occasion of Festpillene i Bergen 2010, a flock of Wind-up Birds has taken over the mountain side of the Fløien mountain. More specifically along the windy, steep path through the spring-green forest called Fløiensvingene. They will probably stay a few weeks. This has created a lot of buzz among the people using the path, so I will try to spend as much time as possible there to listen to audience reactions.

They might sound similar to previous generations, but there has been a few changes under the hood: The wood blocks have this time been milled instead of glued, making them more robust. Thanks to Ivar Bergseth and his CNC mill!

I use a new set of xbee modules, the xbee 2.4 pro digimesh modules. This gives a more stable network and is much easier to work with than the previous firmware.

I made new more practical circuitboards, which I got manufactured at BatchPCB, making the job of assembling the woody boards much easier. This was my first attempt at working with Eagle PCB circuit design software, but I leaned heavily on Roar Sletteland´s previous PCB layout for the first generation.

blink at Sonic Acts XIII in Amsterdam

I am presenting blink at the Sonic Acts festival in Amsterdam. The installation is part of an exhibition that will be on until May 2nd at NIMK.

I have added some images of this version of the installation in my blink flickr set.

The theme of this year´s festival is The Poetics of Space, and the program is packed with audiovisual performances, screenings, a very extensive conference program as well as the exhibition. There is also an accompanying book, which contains the text that Mitchell Whitelaw wrote about my work.

I will be giving a presentation on the last day of the conference.

The program for Sonic Acts is avaible online, but also you can download the programme booklet as PDF.

blink feedback

As expected, the international art press didn´t fly to Bergen to cover my exhibition. Neither did the national press or the local press (with one exception).

However, I did get a lot of positive comments from visitors of all ages (see more of the younger generation´s response here), as well as some feedback from Norwegian art blogs like kunstkritikk and ytter (both in Norwegian).

Create Digital Motion generously mentioned my work, as well as the blog Young Starving, which was just too flattering not to mention :-)

“This is pretty darn beautiful. Projection mappings been done to death but so far most people have just copied each other and done trippy, morphing stuff on castles and libraries. HC Gilje takes a step back and puts two flat surfaces to work. We’re in love.”

blink blink

My exhibition at HKS contained two new installations, both named blink. The first blink has already been mentioned.

In the cellar of the gallery I set up an artificial sundial, 24 leds placed in a circle, moving the shadows of the people standing within the circle.

I used the dimsun lighting system which I made this summer, based on power LEDs and arduino controlled LED drivers (TLC5940).


Last week my exhibition blink opened at HKS in Bergen, Norway. It consists of two new installations and documentation of the main projects I have done during my research fellowship.

In the basement I have a light-sound installation, with 24 bright LEDs placed in a circle in the ceiling, animating the shadow of the visitor.

In the main space I have a video projection-sound installation, where I project into/onto the gallery space.

Since my project the last three years has focused on improvising with spaces, transforming them using image, light and sound, I decided for this exhibition to go all the way and work with two empty spaces.

You can see an excerpt of the projection installation here:

more images of the installation.

I will come back with documentation of the light-shadow installation.

HKS asked the australian artist and writer Mitchell Whitelaw to write a text about my work.
