stereolux

For my performance and installation at Stereolux in Nantes I answered a few questions about my work from Laurent Diouf, chief editor of MCD. The short version will be at stereolux website, but here is the long version:

01_ First, a few sentences about Radiant… about the meaning of this installation… and also about the use of laser and phosphorescent paint…

My work with Radiant started out with some thoughts on extinction, growth and decay, the fascination with how plants create food from light and the material qualities of laser and the phosphorescent pigment. Laser light is more intense than sunlight, and phosporecent pigment are actual natural minerals that are able to capture light and slowly release it as a green glow (In the times of Galileo they were called solar sponges).
Radiant is also much about time and speed: The intense quick drawings of the laser point versus the slowly fading out when the light is released. The interesting things happen in the layering of these drawings, where you can see traces of multiple pasts mixed with fresh drawings: different time scales (or Bergson´s duration) coexist on the surface of the screen.
For the audience I think it works also in a different sense when thinking about scale. It contains both a macro and a micro scale: You could be staring into the universe or be looking at a cell or subatomic processes.

02_ Your works / installations are “conversations with spaces” (with light, projection, sound and motion)… is it the same way for/with Radiant ?

Normally my process is to start with the space where I will make a work, spend time exploring it, using improvisation as a method: I bring my set of tools and start experimenting my way towards a path that creates an interesting amplification or transformation of the space.
With Radiant it is a bit different since I started it out as making a big flat quadratic light painting (the one at Stereolux will be 3.6×3.6m), and not particularly thinking about the space it would be presented in.
However the installation is transformed by the spaces it is presented in, and it also has the power to transform and intensify the spaces it is presented in. It is a quite different setting from a rough concrete environment at Kraftwerk during Berlin Atonal to a circular floor projection with a custom made arced wall in at Kunsthall Grenland in Norway.
Also the light of the white laser beam is quite intense so the resulting shadows in the space is quite similar to my other light installations.

03_ Following the opening of the exhibition, you’ll do a performance. What about this live a/v ? Will you use some elements from the installation in/for your set ?

Radiant started out as an installation, and I always thought of it as a loop piece because of the constant layering of time creating new images, where the installation becomes a place or a state you walk into. As a live performance time is not circular, it has a direction so this changes quite a lot the experience of the piece I think. Also a live set is more of a communal experience while the installation is maybe better experienced alone or with a few people.
The raw material of the installation and the live set is more or less the same, it is the structuring that is the main difference.
Also, the live set introduced the soundtrack, which is created in real time using the amplified mechanical sounds produced by the laser mirrors. The sound from the laser is amplified and played through the speakers, but also recorded and reappearing as new sound layers (similar to the visual material) during the performance.
My exhibition at Stereolux will actually be the first time I will try use this sound setup for the installation as well.
04_ Generally speaking, how do you manage your live’ set ? What do you want to show, to give to the audience through a live A/V. ? Is it also a “space for co-working” with other artists ?

I guess I partly answered that in the previous question, but for me this performance is about creating a focused intensified experience for the audience, in contrast to the installation which is more of a meditative piece.
Almost all of my other live A/V performances are quite different from this one, as they are real time free improvisations with musicians or other visual artists, where the process unfolding through the collaboration is the interesting part.
So Radiant Live is a very controlled piece in that sense, with a quite fixed structure but with room for variations.
05_ If you have some others projects…

I recently created a site specific light installation for four interconnected rooms in a gallery space. The piece was called Red White Black and consisted of two rails of LED strip that followed the contours of the rooms and doorways. One pulse of white light moved in one direction, one pulse of red light moved in the other. Super simple in one way, but it created a very dynamic space of opening and closing, revealing and hiding, a space that expands, collapses, twists and turns in the light from the red and the white pulse of light that chases along the walls, corners and door openings of the space. Probably one of my favourite pieces 🙂

A very different work but which has been my most shown work the last years is Barents (mare incognitum). It is a single channel video installation of the Barents Sea slowly turning around. It was filmed at the border of Norway and Russia with my custom built camera pointing towards the North Pole. It is one of many works that came out of my involvement with the Dark Ecology project; a series of journeys and projects initiated by Sonic Acts and Hilde Mehti in the Norwegian-Russian border area.
Another work that came out the Dark Ecology project was my film rift, combining
my love for the experimental film maker Len Lye and an interest in the deep time of plastic. It was part of the Vertical Cinema program: experimental 35 mm cinemascope films in the vertical format.

Finally I would like to mention speiling, which is the latest in a long series of projection spaces: solid coloured organic forms projected onto a highly reflective floor, creating a dynamic light space.

Right now I am working on two quite different projects: an installation for a stalactite cave in an old fortress to be presented in August, and a series of installations for next year where I give myself the challenge to work with light, sound and motion but in a normally lit space.

06_ Feel free to add or highlight anything you might think relevant.
This is my first solo show in France, although I showed my installation in transit X in Marseille as part of Chroniques Festival in 2017. I have also had a few screenings in various locations in France, including Cinemateque Francaise and Centre Pompidou, due to my involvement with the video art publisher lowave, which released my DVD Cityscapes back in 2005.

I made a book in 2017 documenting many of the Conversations with Spaces projects.
It is available through motto distribution.

romlab workshop

I just finished teaching a two week workshop exploring space using VPT and arduino.

I kept a project blog, romlab2012, which might have a few useful tips for the integration of VPT and arduino. It will be updated with a bit more documentation from the different projects in the near future.

 

VPT 6 available: A projection powerpack

With almost 5000 downloads of VPT 5.1, I am happy to announce that the next version of Video Projection Tools, VPT 6 is now available.

VPT is a powerful and flexible video projection tool that does much more than just mapping.

What´s new in VPT 6.0
A completely new graphical interface making it even simpler to position, scale and distort the layers.
32 layers (previously 16)
mesh distortion with variable-sized control grid.
a completely rewritten cuelist making it even simpler to create transitions and to build complex sequences. You can now also send osc formatted commands directly from the cuelist.
crop-scaling of sources.
increased syphon support with two syphon (crop-scalable) inputs as well as syphon output support (mac only)
a DMX module has been added, with support for Enttecs usbdmx pro interface, enabling both control of VPT from DMX light consoles, or the possibillity to control dmx devices from VPT.

VPT still supports mac and windows, and it is still free. However, I have added the option for contributions through paypal:

VPT 6 is made possible through the support of IMAL in Brussels and Atelier Nord in Oslo.

IMAL offered me a one month residency in april to give a VPT workshop and to do an exhibition.

Atelier Nord has supported me twice this year: First they hosted a workshop as part of Oslo Lux in January which ended up in a VPT 5.1 release, and in june they gave me a week residency to write documentation for VPT 5.5 which instead turned into intense development of VPT 6.

So hosting workshops and inviting me to residencies is another way of supporting my work.

Read more about VPT 6 and try it out

Results from openLAB exhibition at IMAL

In beginning of April IMAL hosted an openLAB workshop called “Projections on forms and spaces”.
The workshop was led by me and was mainly based on using VPT. We selected 7 projects to be realised during one week development at IMAL, and the documentation is now available from IMAL.

It was an intense and interesting week, and interesting to see VPT explored for new uses in installation and performances. A new development for me was to introduce a simple video and audio trigger setup (available in the xtension section), which allowed for some audience interaction, as well as use of the serial module for controlling lights inside sculptures.

VPT workshops

Well, it´s no secret that a shiny new version of VPT is just around the corner.

The first people who get to try this version are the participants of the upcoming VPT workshop in Bergen, hosted by BEK.

The workshop takes place December 6th-9th.
Sign-up information.

As part of the Lux festival in Oslo I will give a workshop hosted by Atelier Nord January 22nd-23rd 2011.
Sign-up information.

In april 2011 IMAL in Brussels will host another workshop. Sign-up information will come later.

makerbot #508

One of the things I was planning to work on during my New York residency was to construct a makerbot, a 3D printer that comes as a kit, based on the reprap which I have written about before. The cupcake cnc, which is the official name, is made by a Brooklyn based company Makerbot Industries that came out of NYCresistor. The first model came out late spring last year, and they continually improve both the mechanical,electrical and software parts for each batch they send out. For about $1000 you get all you need to make your own desktop 3D printer, which sounded like a good way of getting started with digital fabrication.

For me, one of the entrypoints into fabbing has been through reading some of Mitchell Whitelaws postings, for instance Transduction, Transmateriality and Expanded Computing. Chris Anderson wrote a very optimistic article in Wired in January: “In the Next Industrial Revolution, Atoms Are the New Bits“, which is nicely balanced by the maybe more realistic gizmodo article “Atoms Are Not Bits; Wired Is Not A Business Magazine“. A few days ago Thingiverse posted their take on this: “Atoms are Not the New Bits. Yet.

I ordered my kit in december, and in the beginning of february it arrived at my doorstep in Brooklyn. The construction took about a week. The instructions for assembling the makerbot are pretty good (although I had my IKEA moments), but to actually get the makerbot printing was a lot more complicated and frustrating than what I had expected. After trying different things for almost a month with plastic-spaghetti as my only visible result I got a replacement card for the extruder controller (the part which controls the flow of plastic), so last night I was finally able to print something which was very exciting!

The cupcake cnc is made from lasercut plywood and acrylic. It has three stepper motors: The x and y axis are moving the build-platform, the z-axis moves the extruder vertically in relation to the build platform. The printed object is buillt layer by layer:plastic filament is fed into the extruder, which heats it up and squeezes it out similar to a hot-glue gun. The controller is based on the seeduino microcontroller, which is an arduino clone.

To make an object you obviously need a file. The final file is basically a description of operations for the makerbot, controlling the position in the x,y,z axis, as well as temperature and flow of the extruder. You start off with a 3d object, made for instance with blender, sketchup or openscad. This must be exported/converted to the STL format, which can be read by the application that converts the 3D model into slices and produce the controlcode understood by the makerbot. This is done in python-based skeinforge, but some more intuitive tools have started to emerge. The makerbot comes with its own controller software, ReplicatorG, which is very similar to the arduino interface. You can choose to either save the object-code onto a SD-card, or to print the object directly from ReplicatorG.

A good place to start is Thingiverse, where people upload their 3d objects for other people to make. I find it fascinating that I can make my own version of an object somebody else has modeled. I also find the makerbot blog quite useful. Bre Petis, one of the makerbot team, gave a nice presentation(mp4) at Chaos Computer Conference in Berlin in January.

dimsun

The last half year I have been working quite a lot with lights and shadows, and this summer I decided to build my own lighting system, which I called dimsun. The first use of it was for my blink installation consisting of 24 leds placed in a circle.

It consists of dimmers based on the TLC5940 led controllers. Each of the dimmers can control 16 channels, up to 5w each, and are intended for power LEDS, very bright leds up to 5W. The dimmer is controlled by an arduino microcontroller, and up to 6 dimmers (96 channels) can be controlled from one arduino.

more images of the dimsun system.

The schematics will be made available soon.

The lamps are based on starshaped LED´s combined with a lens mounted on an aluminum profile.
