Happy New Year!!!

:D

I guess the New Year eve is pretty globalized now… Everywhere in the world, we see fireworks… And they all look the same…

It’s amazing to see the quantity of fireworks burned in the new year eve in the streets of Holland… Traditional Dutch families spend around 300 euros (it can go until 500 euros, for the midle class)… The day after, the streets are full of… not empty bottles but burnt fireworks… Big difference from my home country (Brazil) where you walk on a sea of empty bottles…

and now more New Year stuff…

Here is a (pretty funny) video I’ve made showing nieuwjaarsduik a freezing diving into hot water (8°C) in Scheveningen… It’s the midday new year celebration, a dutch tradition sponsored by a sauces brand…
I still wonder how was the water…

PS: dutch people seem to have a different and interesting vision of prudishness: after diving, they need to change clothes, and for this you just need to get naked in the middle of everybody on the beach… And no need to hide parts, they don’t really care…

In order to understand a part of dutch culture, I was advised to buy a book of Colin White and Laurie Boucke, both English, called The Undutchables.

Netherlands here I go…

21 December 2007 at 5:22 pm (Exhibition, Links, Un-Usual Post)

I’ll start tomorrow another Netherlands tour. In my plans, I intend to start with the Netherlands Media Art Institute, to see the exhibition Video Vortex.2, in Amsterdam.

Video Vortex.2 Nancy Mauro-Flude

Then, I’ll meet some students from the KABK (Koninklijke Academie van Beeldende Kunsten), an art academy, in The Hague.

Among the museums I intend to visit are the Stedelijk Museum, holding an Andy Warhol exhibition.

I’ll although go to the Boijmans van Beuningen museum in Rotterdam, holding the Surreal Things: Surrealism and Design exhibition and the Paul van der Eerden ‘Enclosures’ exhibition.

Paul van Eerden, Enclosures no. 1, 2002, potlood – kleurpotlood, 20 x 25 cm, courtesy: Galerie Bernard Jordan Paris.

Then I’ll go to the Hague to see different exhibitions (no clear plans yet) and to meet some KABK people. After this, destination : Antwerp Belgium (by the way, it is one of the twin cities with Marseille), to visit the city and the MOMU (MOde MUseum). This is going to be my first time in Belgium, I’m excited about it…

MOMU

Back to the Netherlands, I plan to go to the Groninger museum, I’ll go back to Amsterdam to visit the Rijksmuseum and I’ll finish with the Centraal museum in Utrecht.

As you can see, coming trip is going to be very… Culturaly rewarding and turbulent… So I’ll certainly be posting a lot coming month… I’ll although use my free time to go on into my academy projects with Processing and Pure Data.

Peinture et débordements – Day 1 out of 4 – Morning

19 December 2007 at 12:11 am (School of Art, Semaine thématique)

From the 17th until the 20th of December, we will be having conferences organized by Claire Renier (art historian, artist and teacher of “History and aesthetics of contemporary art” at the Aix en Provence Art School) on the subject of “Painting and it’s overflows“.

We obviously engaged discussions with an introduction made by Claire Renier where she explained the reasons she wanted to organize this conference cycle around this very specific topic: based on her artistic practice in painting, drawing and video, to her experience and contact in art world (meetings with artists and art works that interested her); she observed that contemporary pictorial practice are linked to overflow practice.

By painting overflow, Clair Renier wants to reflect the changes observable in painting : overtaking the frame, moving it and getting the painting away from it. This conferences bring the debate about painting practice, within painting itself but although in other disciplines, like experimental films, sculpture and digital art.

Then Clair Renier presented us some art works to exemplify her concept of painting overflow. By overflowing, she means by adding, subtracting or changing matter, gesture, story, meeting and format.

She started speaking about Philip Guston (here you have a link to an article in English). Here are some of his works :

The color importance, the flatness, the matter addition (for the last painting), the passages between abstraction and pictorial forms and the proximity to comics drawings are some of the aspects of overflow.

Supports Surfaces, a group of artists, known for the equal importance they give to material, creative gestures and final work. This are some of aspects reflect the definition that Claire Renier wanted to give to the overflow in painting concept. That’s a good reason to present a part of their work, here are some of them:

As we can observe here, they totally change the way painting is presented, they change it support: they use walls, frames, fabrics, etc.

Another artist to overflow in painting is Steven Parrino. He builds non conventional frames, with holes, he uses canvas without frame or deliberated fixed with a low tension and he uses bright synthetic inks.

To be honest, there is such a big list of artists and artworks is enormous… So I’ll stop it here for now…

Parkour : art of moving

15 December 2007 at 6:07 pm (Un-Usual Post, Videos)

Today, I saw a reportage in television a documentary, called Vol au dessus des citées, realised by Mark Daniels, showing what Yamakasi is about. Here is a link for the video in French with English subtitles (I loved the documentary).

Yamakasi is a group and association from Paris suburban neighborhoods that practice the art of Parkour. Yamakasi, is not Japanese, and it means strong spirit, strong body. This name was in fact made up in order to sound like Japanese and African… It tries to reflect the multicultural and multi ethnic aspects of French suburban neighborhoods… Le Parkour is a form of corporal art born from a mixture of martial arts, gymnastic, escalation and dance. The urbanism context is although important in the sence that modernist architeture was indirectly responsible for the beginning of the movement. Still, the best way to have a definition is by watching a video by yourself, therefore I invite you to watch this video :

Here is another documentary about Le Parkour and the Yamakasi group :

The reason I think le Parkour is a form of art, is that they have a real aesthetic preoccupation and it is a way to explore and interpret urban space… It represents for theme a way of expression.

PS : Yamakasi were invited by Ariel Zeitoun to produce a film, “Yamakasi – Les samouraïs des temps modernes“, released in April 2001.

PS2: I saw this and thought on Mario Bross jumping… And it made me think on some Billy Elliot scenes too… I wonder why :

Processing: the released books.

12 December 2007 at 12:47 pm (Books, Hypermedia, Links, Processing.org)

Since this summer, two books about Processing code language have been released. The first one was Ira Greenberg‘s approach with the book Processing, Creative Coding and Computational Art, edited by Friendsoft. The second one, edited by the MIT Press, is Processing, A Programing Handbook for Visual Designers and Artists, presents Casey Reas and Bern Fry‘s approach on code learning. There is another book about Processing : Built with Processing written by Takeshi Maekawa (前川 峻志) – who participated to the processing.jp website- and Kotaro Tanaka (田中 孝太郎) and edited by BNN.

Since I neither read and understend Japanese nor have the Built with processing book, I’ll present my impressions and opinion about both Processing Creative Coding and Computational Art and Processing, A Programming Handbook for Visual Designers and Artists books.

Both are learning oriented books, they present and explain the code language structure and how to start building your own programs. The main and obvious difference between both books are the writing style and the pedagogic approach.

Ira Greenberg’s book has a more intuitive approach. He uses a smooth() function for all the technical stuff, showing that math, logic and programming are not that hard and boring. Reading the book you feel like Greenberg speaks with you and tries to reassure the readers. I believe that this book is a good approach for people who want to learn processing, in a creative way, with no programming skills and that are afraid of the computer world, math and programming process.

Casey Reas and Ben Fry’s book has a more technical approach, they use a more technical and formal language and style. They have an extended reference of every single function, in fact the book is an extension from their reference page from the processing website. I would indicate this book more for people who already have some programming skills or people who are not afraid with formulas and computer science and technology.

Another difference between both books is the artistic references presented. In Greenberg’s book, we have a short summary of computational art and a list of some majors artists (like Ben Fry, Jared Tarbell, and others) with a short biography and some links. In Casey Reas and Ben Fry’s book we can find some more interesting material : a preface written by John Maeda (developed Design By Numbers), a set of interviews with artists (like Jared Tarbell, James Paterson and others) about one or two pieces of their work, asking what is the piece about, why they created this piece, what software tools they used to produce the piece, why did they used those tools and why do they choose to work with software. I think this approach is interesting, allowing us to see and understand the backstage of art production.

Biennial of Lyon – Part 4

10 December 2007 at 11:07 pm (Exhibition, Hypermedia, Links, Processing.org, Videos)

Collectif 1.0.3, presented in the MAC and invited by Pierre Joseph, presents Pierre Joseph’s private computer data in the piece Planiscope.

(View of the planiscope version Dominique Blais – 22 august 2005)

This work is a poetic way to present the interface between private and public sphere in the computer world. A computer is a machine that is able to store and process data. Data is a kind of extension of the information concept. I mean, pure information is the analogical values of reality. It is a conceptualization of our perception. By putting together information in logical structures produces data. So the fact to store data is a way to freeze conceptualized information of reality in a given space-time. Therefore, a computer allows you to store a part of your reality conception. And reality conception interpreted by you is reflected in the way you store and organize data. But when you organize data, you first split it in public and private data (not always in a conscient way). A computer has a neutral position with the data that is in it. Therefore, we tend to store all kind of personal data, public and private. But computer has such a big level of neutrality that it stores and presents data from anybody to anybody, with no discrimination or selection. Internet is a computer network to store and transfer data. Therefor, connecting to Internet is the same as to open a quantic portal to the data stored to all the other computers connected to this network. So we can see Internet as the sum of each reality conceptualization. And surfing in the Internet would be the same as to reorganize this data in order to build new data, so new interpretation of reality. Bloging and rebloging is a good example of what I’m trying to explain.

Another piece of Collectif 1.0.3 is Voyage en URL.com where you can download a screen saver exposing your browser historic. Exposing the way you search information and a definition and vision of reality. The way you associate data is a reflexion of how you actually build data.

Another work with an obvious issue link is Life Sharing, by 0100101110101101.org (composed by Eva and Franco Mattes), where they shared their personal computer data in an Internet site. With a point an click graphic interface, users were able to explore their computer arborescence.


Pascal Chirol‘s recent work Hyperonyme guives an visual interpretation of data arborescence, presenting it in an explicit and ponderated graphic form. Still in the same topic, Hard Flowers is an artistic software, built with Processing, that generates a visual representation of the hard disk arborescence. Not showing the actual public and private data, but using it as parameters to build flowers.

This kind of piece shows the information network built by computers and data storage devices. This brings a reflexion to the use of social networks like Facebook, Orkut or mySpace; and to sites like Flicker and Youtube, used to store photo and video data in a public place. Web 2.0 democratizes information and information access but it reveals and exposes our way to concept reality. In fact my very specific blog is in this system, I am here and now exposing my personal vision and interpretation of many art works and exposing my own thoughts and works.

To finish, I hope you like this post, and I hope you share your comments, critics and thoughts about this.

A/V Feedback

10 December 2007 at 12:30 am (Circuit Bending Workshop, Hybrid Workshop, Hypermedia, Processing.org, School of Art, Sound, Videos)

Here is a schedule of my project in the hybrid workshop and sound/hypermedia AOC (Creation Tool Workshop)…

Basically, I see the electronic components of the computer and its structure as a filter to generate and modulate sound. Using a phone pickup coil (a kind of “mic” that is able to register electromagnetic variations some decades ago this kind of material was used to spy phone calls), I listen to the computer electromagnetic variations.

I treat the collected signal with Pure Data, where I digitalise it and send the data to processing, in order to produce a visualisation of the sounds. I want to pick up the signal straight from the video card. Since the computer treats both the audio and the video signal, we can considerate this kind of experience with a kind of A/V feedback.

This work is based on three references. First, the most obvious for me : Alvin Lucier‘s piece, I am sitting in a room (1970). In this piece, Alvin Lucier uses a room as a filter, his voice is deformed by the room acoustic proprieties. In the end, the room is seen as a music instrument.

Another obvious reference is the Feedback exhibition (held in 2007) in Gijón – Spain. Among the art works, the one of the 5voltcore piece : Shockbot Corejulio (2004), a hacked compute, where a robot produces circuit connexions directly on the video card.

Finally, once again, Nicola Collins‘ workshop about circuit bending and work with feedback is my last reference.

To finish, I’ve made a small animation as a schedule for my project, here are the details :

High Voltage Circuit Bending

9 December 2007 at 2:58 pm (Circuit Bending Workshop, Hybrid Workshop, Links, Mechatronics, Sound, Videos)

Here is an example of high voltage (HV) circuit bending: a keyboard connected to a tesla coil. When you play a note, the tesla coil is activated. I don’t know how dangerous this is… so… I don’t know if it is a good idea to do it…

Still in the HV theme, here is another video of what we can built with a HV Power Supply (more then 30k volts): we can build lifters. Basically, when the 30kV field is generated, the air around the anode and cathode gets ionized and start to create an unstable plasma gas vertex. When the air particles hit the aluminum sheet, a small force is generated, when you make the sum of all the forces, the structure starts to lift. To build a HV Power Supply, you can use and modify an old cathodic tube. Here, you can find how to build your own lifter (be careful please…) and here you can find some theories about how lifters work…

Well, here are videos of lifters, enjoy it:

And now with some speech:

Programming, sound and moving

9 December 2007 at 2:18 pm (Hybrid Workshop, Hypermedia, Mechatronics, Processing.org, Sound, Videos)

During the Sound/Hypermedia acquisition workshops we had to think on a project using the Wiimote, processing and sound.

Well, here is a video showing what can be done with accelerometers, programming skills and sound production:
