Blind Theatre workshop

Jonas Jongejan — Sun, 03 May 2009 17:46:01 +0000

I have just finished 2 weeks of workshop in Oslo together with Ståle Stenslie, where we have been working on a theatrepiece Ståle is doing in september in Oslo. The play is going to have 5 stories the audience can listen to, and at the same time the audience will (one at the time) have a speciel suit on with 64 vibrators (like the ones in mobile phones), and some sensors. And it is this suit i have been working on. First of all making the electronics (controlled by a Arduinio) work, and secondly making a application (in Processing) to design the “animations” that are going to run on the suit together with the recordings of the stories.

Later we are going to add interactive elements to the timelines that are created with this application. But for now the people in Oslo will work with this and the test suits we got until i come back.

Organic programming

I have been playing around with perlin noise in processing, and come up with some pretty organic worms i think. Not rocket science, but funny to look at

Stop Motion @ RE:NEW

RE:NEW Festival, Copenhagen central square, summer 2008
With extremely short warning I was invited to make something on a huge LED screen that was put up by a electronic music conference in Copenhagen. They had in the last minute got money to built this 8m tall LED video monolith on the central square in Copenhagen for 2 days, and they needed people to make something on it. So Ole Kristensen and I developed in one week an art work called Stop Motion that was developed for this screen. The concept of the art work is a interactive non timeline based stop motion “movie” that is developed over time. On the screen you see a person stand with an ordinary lightbulb in his hand, and from the air there is hanging a lightbulb down. When you take up the lightbulb yourself and move it around in the air, you see a marker move around on the screen in the same way as the bulb, and at the same time images of other people holding the bulb at the same spot as you do are loading on the screen. When you hit a spot where there has not been taken any photos, a countdown begins, and a camera takes a photo of you, and add you to the grid of images of people holding the lighting bulb.

People really enjoyed playing with the piece, and see them self projected on a big big screen on a spot where many people walks by, and come by later and see them self again.

Because it was made in so little time, it was suffering many technical problems in the begin. We made it in Processing, and the first major major problem with processing is the limit of RAM. We had to save the images in the computers ram, but when we used more then 2 gigabytes of ram it crashed. And loading from harddrive was way to slow. In a later version of this application we ported it to OpenFrameworks witch solved our problems.

Body navigation

Recoil Performance Group, spring 2008
Choreographer Tina Tarpgaard, Recoil Performance and my good friend, programmer Ole Kristensen invited me to help them create body navigation. The body navigation performance was originally part of a larger installation and modern dance performance in copenhagen, by Tim Rushton, Danish Dance Theatre called Labyrint. We had one room out of five rooms to make body navigation in.

Body navigation is a reactive floor-projection where dancers can dance on together with a digital reproduction of themselves. It consist of a camera tracking the dancers on the floor, and a projector that creates a image on the floor around and on the dancers. With this system we where able to create connections and visual images about human relations and emotions that where not otherwise possible.

Ole and I developed a application built in Processing based on a concept developed by Tina Tarpgaard and Ole to track the dancers and create the visuals projected down again. All controlled live by Tina with a control panel developed with Isadora under the performances.
