ENTROPY v2.0

Conceptualised by Kasia Molga & Bram Snijders, produced by Kasia Molga and Erik Overmeire

“ENTROPY” is a participatory interactive space and object-based installation, where what is normally perceived as “digital” and “virtual” entity is transferred to the “real” and “analogue” so that viewers can play with real time data visualisation at the same time influencing that data.

“ENTROPY” corresponds to the concept of production, emission and consumption of heat (and thus energy) in “ordered” and “un-ordered” manner (corresponding to the definition of the entropy phenomena). Through that the installation questions issues of production and consumption of energy and its emission and transmission and the human relation to a concept of energy on global and very intimate level. It involves real time data visualisations aimed to provide in such a way so that viewers can have an intimate, tangible and tactile relation/interaction with something as abstract as data. As such it also explores data (as real time feeds) as an independent force making the artwork alive. It also plays with mixing “digital” and “virtual” making it tangible in “analogue” and “real” space.

Audience enters the embedded within the exhibition setting. The interaction is natural and unexpected, and the main agent between data visualisation and a viewer is a simple everyday object mostly associated with energy – a light bulb. By interacting with it – moving closer or touching it with a hand, the energy in a form of on-body projection mapping is transmitted onto a viewer – so that a data is “placed”on a viewer making her/him a carrier/transmitter of it. The “energy” then can be transmitted between one person and another as well as spilled in the environment.

The real time data feeds is from a number of hacked data sources (for “global energy”) and from the arduino sensors placed within the exhibition space. Through the choice of technology live feeds come to “live” being picked up, spread/transmitted around by viewers, making them partially responsible for that data and thus their own experience.
“ENTROPY” takes the act of interaction with that data and motion based mapping – which not only happens on moving objects, but can be transferred from one object to the other – so that new interpretations, meanings can be created and perception of the world can be transformed.

Photographer Frans van Viegen commisioned me to write a piece of software for him which allowed him to present his work with in an interactive setting.
The software was written with openframeworks and uses a xbox kinect depth camera as image sensor.

During the developement of this project I needed to read metadata from image files, but I could not find any openframeworks addon which could do that. So i made one based on the exiv2 library

3D Scanner

For Moddr_/Worm i developed a kinect based 3d scanner. I used a line laser to point out the points to be scanned and a rotating platform to get a 360 degree scan of an object. It could scan objects of around 20cm x 20cm x 20cm

BCI-24_BLACK

lifthoofd — Sun, 08 Jan 2012 01:52:05 +0000

“BCI-24_BLACK” is part of a slowly growing collection of printed works that find their origin in some sort of coming together of a scanner and printer.
For “BCI-24_BLACK, I printed a completely black piece of paper and kept repeating this until the inkcartridge was empty and the printer gave some error stating that it could not continue anymore. After the printing I scanned every piece of paper back in to the computer and combined them in one long image that measures 20 cm by 255 cm.

A vj program for 4 screens in max/msp, commissioned by Geert Mul.

Photo’s and the first video are from “Harbour”, the second video is from “Sound of Identity”, both are performances by Michel Banabila and Geert Mul.

8-bit wav

8 plexiglass prints placed in the form of a wave, the images are generated by a program I made for a vj-performance. 8 bit wav is a collaboration with Dennis de Bel, made for the “Ongekend” exhibit during Art Amsterdam at Trouw

this work is for sale, contact me when interested

A one day workshop about the basics of motiontracking in max/msp, during the exhibition “Digitaal” at BKKC in Tilburg. At the sametime a demo version of the BaltanTracker was shown as part of the exhibit

interrupt

lifthoofd — Mon, 21 Jun 2010 18:43:08 +0000

Interrupt is an installation that takes Cambrian Explosion (another one of my projects, done together with Dennis de Bel) as a starting point. The conversation between the two computers is no longer limited to interacting between eachother, they have gained the the ability of sight.

When visitors walk in between the two screens they disturb the conversation by their presence. By showing that the computers know where the visitors are walking and changing the sound that is generated (read: changing the tone of their voice) they try to warn the visitors of. Like this the visitor becomes part of their conversation.

cambrian explosion

In this installation two computers are involved in an intricate evolutionary debate, creating a dynamic, ever-evolving collage of sound an image.

The piece consists of a beamer, a screen, two computers and audio speakers. The two computers communicate to each other using sound based on the visuals they create. One computer receives the sound of the other and creates a three dimensional entity based on this sound. The 3d image is then translated to sound again by the computers specific algorithm. This new sound is then send to the other computer which repeats the same process. Each iteration builds upon another, creating an ever evolving play of shape and sound.

Cambrian Explosion is a collaboration with Dennis de Bel and has been shown at the TESTnula Festival in Zagreb, Croatia and at the Counter Culture Festival in Holland

Artist Geert Mul and programmer Erik Overmeire developed the Baltan Tracker, a hardware / software combination for motion tracking of persons in a space. Normally this kind of motion tracking is being done using normal or near-infrared cameras. This is can be problematic due to the fact that any form of incoming light or any kind of object might be mistaken for a ‘person’. The Baltan Tracker uses a thermographic camera, which prevents a lot of these light related misinterpretations because the camera is heat-sensitive. In fact it does not see ‘light’ at all, only infrared radiation (heat).

The BaltanTrackerwas commisioned by Baltan Laboratories.

Erik Overmeire has lead a workshop on 21-10-2010 at BKKC in Tilburg, using the Baltan Tracker as a starting point to explore the use and possibilities of motion tracking for artists.
Erik will explain the basic components of any motion tracker and the max/msp library the participants will be using, and then invite the participants to make a simple work using the motion tracking tools and knowledge they have gained in the workshop.
