OFFF 2011 Barcelona - Aaron Koblin

16.06.11 Max Novakovic

'Aaron Koblin: Let's feed the future workshop' was probably the talk I was most looking forward to at OFFF. It focussed on a workshop available for a select few where the attendees would 'work together for one day and present their creations'. I will be covering the results of this workshop in another post, but I think Koblin's introduction to his work and himself warranted a separate blog post.

Aaron Koblin is 'an artist specializing in data and digital technologies'; he is also Creative Director of the Data Arts Team at Google. At OFFF before the workshop attendees presented their work, Koblin gave a brief overview of some of his works. Some projects he mentioned were:

The Johnny Cash project is an interactive music video in which each frame is drawn by a different person. A user will get a frame of the music video and they can then use the drawing tool on the website to re-create the frame in whatever style they choose; limited to a black and white palette. The video at the top right of this post is a version of the music video. Since the video is ever changing, it will probably now be different so go to the website and see it for yourself. Another interesting feature of the project is that frames can be categorised and rated so you can view the video differently based on frame rating, abstract frames, realistic frames, etc.

The video for Radiohead's House of Cards (credits) which used lasers to capture surroundings and shapes to produce a music video that didn't have any video in. You can download the source (written in Processing) and watch a making of video at the Google code page. Koblin also explained how because the video was open source, many spin-off versions of the video had been made and uploaded to youtube including a 3D print of Thom Yorke's face, see image to the right.

eCloud is a sculpture/permanent installation housed inside San Jose International Airport. It features hundreds of panes of 'Smart glass' which are turned on and off to simulate weather patterns around the world. There is a display which details what is being displayed on the panels. There is a lot of information about this at http://www.ecloudproject.com/. The photo to the right (by Spencer Lowell) shows the eCloud installed in the airport there is also a video of it in action here. This project was built in Java and was built using Processing as a base.

Others were ROME which is a completely browser-based music video which makes use of webGL to create realtime 3D graphics, videos and interaction to create an immersive experience. As Aaron said, you really need to see it yourself to experience it so visit the site: http://www.ro.me/.
The Wilderness Downtown another browser-based music video that uses google maps to personalise the music video, features a drawing tool to send messages to your past self and makes use of browser windows to frame different parts of the video.
Finally, Ten Thousand Cents which was a project that used Amazon's Mechanical Turk to ask thousands of people to draw a fraction of a one-hundred dollar bill. The result can be seen in the animated gif to the right.

To see more work of Aaron's, visit his portofolio at http://www.aaronkoblin.com/, it's all really impressive work. I like to see that Processing is used in many of his projects. Also, I think that my favourite projects of his are those in association with Chris Milk and Mr. Doob - ROME, The wilderness downton and The Johnny Cash project.

OFFF 2011 Barcelona - the geeky gist

13.06.11 George Profenza

Back from an amazing conference and an amazing city. A breath of fresh air is clearly helpful. Maybe it's beautiful Barcelona, maybe the nice weather, the relaxed, beautiful people, but OFFF has a very nice vibe to it. It's so different from geekier conferences and I like it.

Even if OFFF seems to focus more on design, animation and motion graphics, this year I saw showcases of quite a few projects that blended art, design and technology into one.

I will go through a few of the more technical projects showcased at OFFF.

Aside from the technical talk by Aaron Koblin, Ricardo Cabello (mrdoob), Filip Visnjic (CAN) and Eduard Prats Molner, which Max will cover in more detail OFFF also had a brilliant exhibition called Mirrors. This gallery presented a large amount of brilliant works by Kyle McDonald, Zach Liberman, Theo Watson, Daito Manabe, Motoi Ishibashi, Aram Barthol, Marnix de Nijs, Seth Hunter, Eric Rosenbaum and Joshua Davis.

Daito Manabe and Motoi Ishibashi had two brilliant pieces: Points and Fade Out. Points uses a kinect to track the outline of the visitor. Points are computed from the outline and converted into optimal paths for the actuators/motors controlling a compressed air gun. The gun then 'draws' the outline of the tracked visitor on paper.

Fade Out is another brilliant way to digitally draw a portrait: it uses a laser which gradually illuminates a screen filled with phosphorescent paint. Personally, I enjoyed the sound of it and the ephemeral feel the fade out gives to this piece.

Recently I got interested in 3D scanning and 3D printing, as you might have noticed form my previous posts, so I was very pleased to see and experience the Janus machine at OFFFMatica. I was lucky enough to meet Kyle McDonald and talk to him about the project. Got very interesting insights and left inspired to learn more about computer vision, even if, I must admit, topics like AI and Machine learning scare me. The Janus machine uses a 3D scanning technique called structured light. Roughly speaking the idea is light is projected in patterns (a narrow band of vertical stripes for example) onto a subject. The pattern gets distorted on the subject and the 3d data is estimated by using the differences between the distorted and the original pattern. Kyle has an open source project on Google Code called structured-light.

The great things about conferences is you can meet and talk to the people you admire, receive great advices and get inspired. I had the pleasure to chat to Daito Manabe and Kyle McDonald on my 1st day at OFFF which was great. I really hoped to see the illusive mr.doob, but didn't have a chance. I've managed to catch Aaron Koblin for a few questions and a big thank you for the work he and mr.doob have done on the Rome project. I've learned a lot from it and they make it look so easy, but a lot of work went into that. Han Hoogerbrugge put this into words very well: "It's nice to see the people behind the other side of the computer screen".

OFFF 2011 was a great experience, and from the geeky point of view, it proved that the trend of art and technology blending is only going to grow. Makes me wonder how long until the boundary completely disappears.
