The Light Collective: Illuminating the World’s Connections
(Full Interview by Treetrunkwise)
Austin independent film, Otis Under Sky, has not only captured the attention of the SXSW Film festival, it also has the SXSW Interactive community buzzing. The film features a light sculpture that represents the collective consciousness and connections between people.
The sculpture is made up of thousands of optical fibers and electroluminescent wire, whose light patterns are controlled in real-time by an Arduino connected to social networks. Sound like a mouthful? Otis Under Sky creator and director, Anlo Sepulveda, interactive designer, Per Nilsson, and custom software creator, Andrew Duhan, enlighten us.

TTW: Where did the idea come from and does this thing have a name? A working title?
Anlo: It is an interactive light sculpture the people behind it are called the Light Collective. Originally Otis was going to film and post on the internet a fake act of self-emilation (setting yourself alight) to call attention to war and suffering. I decided to go with a less dramatic and a more peaceable way to reflect positive energy into the world. My friend Paul Collins is a conceptual designer so I discussed the Interactive light project with him. We decided it should reflect positive energy by having a website where users could physically click the page to effect the light project. Then I met Per Nilson, an interactive designer, and I had no idea how to make this concept, and Per was able to take the idea and make this reality of it. The more we worked with it, the more we learned to manipulate it. Now it is capable of having different data streams reflected in the sculpture.
TTW: Who were the main people in the think tank for this project?
Anlo: Paul and I birthed the idea and he developed a simple web-based design. I met Per Nilson and his wife Rachael at a music festival and Rachael said “Yeah you should talk to my husband and Per said, ”Yeah I know how to do that.” Andrew Duhan came on board as the technical designer to develop the functionality hardware, and all of them together will develop the algorithms and use their electronic wizardry to make the project glow. There were a lot of people instrumental in helping with the workload, like Johnny Villareal and Corey Sepulveda who helped assemble the physical project. Sean Gaulager from the Co-lab gave us some perspective on showing the installation and allowed us to use the Co-lab for our first art exhibition.
TTW: Without giving anything away, can you talk about the piece from the main character's point of view? Does Otis change the project from its original intent?
Anlo: Otis wants to build a reflection of the positive energy that lives in the digital realm in a way that it hasn’t been done. For Otis, this is an existential project that evolves as his ideas about the world around him evolve. The project is in part finished, and is in part, still happening. Since its inception the potential for it to evolve and be productive and interactive has grown. There are so many different potential data inputs on the internet and its still being developed. Who knows what it will look like in 5-10 years from now. That is what is exciting about it--it is a static and immediate reflection of the positive energy of our existence.
TTW: You didn't just make a movie prop--you made an entire living art project. What inspired you to take this prop to the next level?
Anlo: We came up with the concept for the film and had to make the prop but because it was such a beautiful idea we figured we might as well make it real. I like a film to be more than just a film. There’s the vlogs that can exist on the internet and be its own thing. Even the music can live outside the film. Instead of having a narrow self-focused thing I wanted to make multiple components live outside the film.
TTW: Will the installation live on after the festival?
Anlo: Yes. Definitely. I hope the film helps pique interest in the installation and it will continue to live and evolve and to connect to other users who will try to affect the data stream. You can watch the film, go home and find the art project on the internet, and know that your data stream is affecting the glow of the light collective. I hope it creates its own legacy and the two, the art project and the film, can sort of prop each other up, like if you go to the film you will hear about the art project, and if you discover the light collective, you will hear about the film. Everything all connected.
TTW: Anything you'd like to add?
Anlo: The most critial thing is that this is an extremly colloborative project. Without people contributing time and creativity this light project could not exist and becomes ineffective. Its a group of writers, actors, and interactive artists who have created this dynamic thing that helps other people to connect. The sum of parts is greater than the whole. There is no way to conceive something like this on my own, and it could not have happened with out everyone’s help, and the project itself is useless without the energy of all the people on the internet and this planet. This whole thing is about connecting people with other people and to reflect the beauty of that.
TTW: Hi, guys. Per, you were the first part of the team brought on by the film’s director, Anlo Sepulveda. How did that come about?
Per: I met Anlo at a music + art festival called Art Outside in 2008. He was running this amazing stop-motion animation station in the middle of a field, where anyone could come up and make claymation shorts. My wife and I struck up a conversation with him, and told us he was working on a movie and needed someone to build him a light installation. We started planning the work right away!
TTW: And how did you become involved with the project, Andrew?
Andrew: I'd seen the first version when it hung in Co-Lab (an East Austin Art Space where it was on display to the public) and immediately started dreaming of the possibilities. It actually inspired me to learn quite a bit more about microprocessors and higher-power circuits. A short time later, Anlo contacted me and asked if I could help bring the piece closer to the final vision and of course I jumped at the idea.
TTW: Can you describe the installation physically- what it looks like, what it’s made of?
Per: It’s made of over 2000 strands of optic fibers- yes, I counted. They’re cut at different lengths, distributed throughout a large space, and then suspended from the ceiling. It kinda looks like stars- or underwater fluorescent plankton. From a central light are hanging a couple hundred feet of electroluminescent wire, which is a phosphorous-coated wire that glows when you apply a high-frequency AC current through it.
TTW: How does it actually work?
Andrew: The installation is driven by a circuit built around a microcontroller using the open-source Arduino platform. Bundles of fiber optic cable are lit by super-bright LED and spread throughout the space. The LEDs and Electroluminescent wire are controlled and dimmed individually within a matrix. The system interprets the data it receives and translates the values into a visual experience.
TTW: From a technological or programming standpoint, can you tell us why this is an original or relevant idea?
Per: I don’t know that you can say that anything in programming is original, but the combination of using software PWM (Pulse Width Modulation) and light effect algorithms across a massive amount of light points is one example of the Arduino’s versatility. The idea that the collective consciousness, or the "health" of people's thoughts, can be represented as points of lights in a three-dimensional space is relevant from an information visualization perspective. First and foremost, though, it's an art piece, and should be regarded as such.
TTW: The light sculpture in the film was originally built in an art space in East Austin (Co-Lab) where it was on view to the public. How did people react to it?
Per: Very positively! You could see people "swimming" through the lights, laying underneath the installation gazing up, and walking through it with their eyes closed, feeling the optic fibers brushing against their faces. The interaction was purely visual and tactile back then- the light patterns were manually controlled, rather than data-controlled.
TTW: How has the technology changed since you began working on this project back in 2008?
Per: The availability and robustness of real-time APIs, like Twitter's search API, makes it possible to let the installation reflect the "pulse" of certain parts of the online community. The concept of the installation is to represent people's thoughts and prayers around the world. The challenge, then, is how to make this connection obvious to the audience. We are experimenting with different inputs, including sensors in the installation space itself, providing direct feedback to the audience interacting with the lights. To me, the most important thing is to provide our audience with a dazzling and immersive display of lights.
TTW: How will the installation change for the SXSW festival. Is it bigger? Does it represent something different?
Per: From a technical standpoint, we are adding more channels. More channels means more fine-grained control of the lights, and we'll be able to create more interesting effects within the space of the installation. We will customize the layout depending on the space, so the installation will look different every time it’s set up. The effects in the first version were driven by a light sequencer written in Pure Data. This time around, the effects will be natively coded on the Arduino board for better performance. Also, for the new version, we want to make the installation react to people's presence. We'll be adding either ultrasonic rangefinders, or implementing some sort of blob detection.
