break the wall -- network objects

Break the Wall

collaborated with sunghun kim and elim cheng

project URL:

a kinetic performance of a wrecking ball hitting the wall. the performance is controlled by internet users' clicking the button on the "breakthewall" website. every 10 clicks (either 10 people from the internet clicking, or 1 person obsessively clicking 10 times) will trigger 1 hitting action. the performance will be broadcasted through ip camera to the internet. so your tiny action online will have real impact on the real life.

this is the interface you'll see in your browser, either sitting in the quiet office, in front of your depressing boss, desperately trying to find a way to escape behind your screen, or in seattle, on the bus, having nothing to do, thinking of seeing how wall is doing in new york with you iphone.

some of you may wonder where is the wall exactly, and "da da da da! "here it is!!

So Obsessed with ______

Project Brief:

Randomness and Rhizomes

Project: Rhizome
Assignment length: 2 weeks
Due Date: Dec 1
# of collaborators: solo/duo

Make a database that tells a cinematic story. How we access it is up to you – it can be computer-based, or real-world based, or a mix.
The content and form should be working together to covey your concept.

Why random access? What advantages can this have for your concept?
Do you still use plot? Events?

I did a project called "i am so obsessed with ______" .

i want to experiment my thoughts around this obsession project, and i want to get more data from people, and use different criteria to classify those data to look at those data, e.g. emotional involvement; moral judgment, good or bad; socially acceptable or not. I wanna to make people think about their obsessions, especially for people who has obsessive compulsive disorder, who couldn't control and who blame or feel guilty for their obsessions, I want them to go through the process like a routine and take their time to classify, to think about their obsessions, are they really bad? not socially acceptable? or it's just a way how to you look at it.

setting up a scene as a routine, put the objects in the right place, creating a linear space, so people come and automatically follow the rule created by the space.
creating a safe and private atmosphere(i guess i should adapt my setting coz it's not private enough)
guiding people to write down their obsessions using different colors
guiding people to put them into either good/or bad jars
turning everything complex to a cup of "tea" with color, as the Tibetan healing ceremony , mandala http://www.asia.si.edu/exhibitions/online/mandala/default.htm

I got feedback from ithai, "that doesn't make sense, that's not tea" and then I started thinking about it, what if I did relate that with real tea, but use different colors of tea, mix them together and have real tea, does that make people feel more pleasant?
Also eddie said " the classification of both color/emotion and good/bad is confused". I think this performance is an experiment for me to see which is more interesting, emotion attachment or judgment on good/bad. And rating the obsession as good/bad, and attaching the obsession with emotion are two different things for me.
Marina also said "too many texts on instructions", and Allistar knew my project, having the same concern. The test in the bar showed I should definitely make it as simple as 2 steps, write and drop.
Got feedbacks from Marina and other people on using so many different colors to represent emotion. first, that's very personal; second, i have a lot "pink" and it could be biased. so maybe people will not buy the part of emotion thing.
marina also refers me to 12steps, http://www.12step.org/Forums/. That's fascinating, and I found http://www.myrecoveryspace.com/ from 12steps. I've been thinking a lot, should I continue it to make it on line? or more of a face-to-face and reallife performance thing. The good thing for this 12 steps and myrecoverspace project is it creates a empathy "We are more alike than we are different". That's great to people who need mental support.
People are interested in learning others' obsessions, especially if they know that's classified by the writer as good, even they feel that's bad "the obsessed with money one" . then the conflict creates conversation. that's what I like.
I talked with Marina about the direction of this project. I explained I am more focusing on the obsession content, on people's judgment on these obsessions, obsessions on consuming, obsessions on relationship, than the form I did. Advices from Marina are: setting up the place, more specific, asking the question more specific, setting up in a luxury mall vs. in the subway will be different, and I could get more specific obsessions from this specific group of people, and the questions could be even more constraint than right now. Getting more data from different location and different people group would be my next step. I still need to think about the form later and I also would think about involving my own stories into the performance.


reading note: capital by marx


A critique of politial economy

Karl marx

Value :

Intrisic value

Use value

Exchange value

A commodity is first an external object, satisfies human needs, no matter for stomach or for brain, feeling. That's why we consume. Need more, consume more.

Emotional need, as people are obsessed with niky, gucci, apple, etc, people are emotionally obsessed with those brands, luxuries, etc. people need it, and make the exchange value increase, the higher the exchange value, the more emotionally satisfied people feel, and the more they consume, and the more people in the society consume, that's the luxury industry.

My friend told me whenever he is emotionally up/down, or feel lonely (since the capitalism society is a competitive society, and it lacks compassion and it is easy to get lonely), he buys stuff, and good stuff, spends a lot of money. Not sure if that fits to everyone in this system, but interesting point, though.

The usefulness of a thing, or a person. Social capital. Kinda sad, but that's how the society work… where is the compassion, where is the love/??

Technology reduces the labor hour, but the salary of average workers still the same, thus the remaining value workers create increase.

Where is money coming from? Coat and the linen.

The value form, the fetish, is unfamiliar, magic, animating the object.

Exchange Value cames from the social relationships between commodities.all about relationships, the global trading: export/import

The two cow joke: JAPANESE CORPORATION, You have two cows. You redesign them so they are one-tenth the size of an ordinary cow and produce twenty times the milk. You then create clever cow cartoon images called Cowkimon and market them Worldwide.

Japaness cartoon as commodity fetish.

A question, the intrinsic and use value of digital objects, e.g. email service. Or mobile service ?

The virtual QQ coin, the virtual money, as fetish objects in virtual world.

Yahoo as a corporation, putting profit as the highest priority, sacrificing customer's privacy and turned the customer, a dissent to the chinese government. In capitalism, corporation moral is to gain profit.

if table could dance, if coat could speak, uncanny.


Reframe: dead leaves growing up to be flame

Project: Remix/Reframe
Assignment length: 2 weeks
Due Date: Nov 10

"Artists today program forms more than they compose them: rather than transfigure a raw element (blank canvas, clay, etc.), they remix available forms and make use of data."

– Nicolas Bourriaud, Post-Production (p.8)

“Visual, sound, and text collage, for many centuries relatively fugitive traditions (a cento here, a folk pastiche there) became explosively central to a series of movements passing through Modernism to Postmodernism: Futurism, Cubism, Dada, Musique Concrete, Situationism, Pop, and Appropriation. In fact, collage, the common denominator in that list, might be called the art form of the 20th century, never mind the 21st. But forget, for the moment, chronologys, schools, or even centuries. As examples accumulate – Igor Stravinsky’s music and Daniel Johnston’s, Francis Bacon’s paintings, and Henry Darger’s, the novels of and the Oulipou group and of Hannah Crafts (the runaway-slave author who pillaged Dickens’ Bleak House to write The Bondwoman’s Narrative), as well as cherished texts that nonetheless tremble on the brink of outcast status for the subsequent discovery of their “plagiarized” elements, like Richard Condon’s novels and Martin Luther King Junior’s sermons – it may seem that collage and appropriation, mimicry, quotation, allusion and sublimated collaboration are the sine qua non of the creative act, a native urge cutting across all boundaries, forms and genres, across high and low, through both self-consciously sophisticated and “primitive” attempts to make those useless and essential artifacts we call culture.”

– Jonathan Letham, The Ecstasy of Influence

Ruleset: The terms of this assignment are simple.
Create a Remix, in which the content and form are reflected in each other.
The original(s) should be recognizable, but you should think about saying something new in your reframing/remixing of the original material.
As usual in ISCO, this cannot be a single channel work that appears on an unmodified screen, projection, monitor, etc.

I worked together with eddie and what we want to do is a remix of life and death, nature and civilization, the intrisic system of leaves and the system of fire, reframing the dry leaves, play with as if they are color pixels, to create a site specific nature graffiti. Also, we want to create a linear narrative, as people walking from faraway to close by, we want to play around the reversal recognition, making people feel those are leaves on actually fire, while afterward, realize that's just leaf graffiti.

This is our ideal site to put this piece.

Eddie and I tried to put it outside, but we failed due to the wind, the material.

Marina and our classmates' critique made us rethink of our project.
1, negative feeling in terms of the material: it's really true that using tape lost all the magic of this project. we missed the detail and we'd love to tie or sew the leaves on the net if we do it again, outside.
2, magic of the project: i understand that after marina pointing out the lost of the magic for our project. i feel our project is pursuing something really literal: reversal recognition, and ignore something subtle: visible vs. invisible; magic.
3, it's totally different if we put it outside, in a site, like the washington square park. that's our initial idea. we forgot to mention that. gallery setting gives people totally another experience. and we also would love people to experience in a linear way, from far, to closer, closer, so we should control the environment, so that people's interaction, distance will be controlled to fit our purpose. that's also what i see, the magic of the project, and how to play with the physical setting to affect people's behavior.


Pineapple Man with the Earphone and a Piece of Newspaper

Beauties, Specters, and Monsters

Project: Portrait of…

Character. Archetype vs. stereotype vs. individual. Cardboard character. Fully fleshed out character.

This next assignment focuses on the challenges of character development. Much of a character’s depth is realized through a combination of its actions, interactions, and supplementary behaviors.
In cinema, a character unfolds over time.
A character is revealed by his/her/its actions.
In media or installation, a character often has to reveal itself in new ways that are non-linear or multi-linear.
Every work – whether that is a Kleenex box, a doorknob, a mascot, or a story’s protagonist has a character to it, that’s made up of its material, content, expression, and environment. This assignment should bring your scrutiny of all the elements that comprise character to the foreground.
Create a portrait. It could be a real or fictional character, or a chimera – a mythical composite beast.
Your project must contain two or three distinct points of view (literal views, time frames, scales, positions, perspectives, or opinions).
Components: 2-3 screens, 2-3 soundtracks, or 2-3 objects or forms. You must make multiples of the same type of medium (i.e. all screens, all toys, all tape decks, all talking shoes).
Ancillary material: Accompanying this should be a 1-3 paragraph character description. You should draw from the character shopping list or hand-out on characyter development. You will make this available to the class.
Questions: What is the central problem or thesis the character wishes to express?
How is your portrait cinematic? Are you dealing with color, tempo, lighting, atmosphere, and scene to help give a sense of this persona?
How are you characterizing your subject? How is she/he/it round, not flat?
Are you alluding to any particular narrative genres?
What are we gaining in character depth, contradiction, or narrative viewpoints from having more than one perspective? How do multiple viewpoints or iterations help make your character “round?”

---- by Prof. Marina Zurkow

For my Interactive Screen and Cinematic Object class, I created a character: Pineapple Man with the Earphone and a Piece of Newspaper.

An old man, sitting on a bench in Washington park in the dark area under the tree, really faraway to see clearly except that his size is big, and he is holding a newspaper, covering his face. Walking closer by, his face is sort of greenish, seems really not smooth at all, with a pair of dark sun glasses, you know, it 's night time… I say "hi" to him, seems he doesn't hear. Oh… I see, he has a big black earphone covering his ears and a piece of "New York Times" in hand. Seems a knowledgeable professor in Politics or Law or Business, I don't know.

While getting closer to him quietly seems doesn't bother him. He is too focus to even notice me.

He keeps nodding as if he reads something important or hears something satisfying. What is he reading and listening?

"Many Health in Disclosure of Nominees’ Holes

By Lawrence Altman

The limited candidates provided by the information is a striking campaign from recent departure in a year when their significance carries extraordinary health... "

Audience Reaction and Critique

After encountering with my pineapple man, audience associated the character with different figures: old man sitting in the park, vacation guy relaxing, woman in 80's since the sun glasses look like that period, or could be anyone... Whether the character is a male or female?
Actually, it is a type of people. It actually could be anyone. That's actually my reflection after the critique. But while before the critique, in order to make my character specific and easy to recognize and describe, I want to make the character as an old man as a professor or so. The problems with this character is (from marina and my classmate's critique) :

1, pineapple associates with vacation, Hawaii, and party. as marina and others pointed, as a sculpture, audience always tries to find the symbolic feature and each of them will affect how they perceive the sculpture. I totally feel I should make decisions by putting myself into the role of the audience, coz this pineapple, for me , i associate it with ugly figure, and it seems just me. so to improve the project, also to reflect "it could be everyone or part of everyone" I want to replace the pineapple with a white ball, generic face; OR I want to create 3 or 4 fruit heads, e.g. pineapple, banana, and watermelon. First to make people think that's actually not just this figure, but different people that could belong to this type. Second, to reduce the association of pineapple.

2 sun glasses should be selected carefully. again, that plus the pineapple makes the character more like a vacation guy to the audience.

3 the newspaper: I am happy most of people got the idea and burst into laugh after reading it. the sound: radio news . some people got it, while others didn't hear anything strange. Hulya burst into laugh when she posited the earphone and she pointed out the interesting thing was she realized she was in a conversation with a pineapple. Steven piointed out the consistancy between the newspaper's nonsense and the radio's nonsense. Some people feel the character is making an ironic statement on politics, and Marina feels the character is an alien or a blind voter trying to figure out the "no-way-to-understand" election, I thought that's interesting and also Jose said, that is same as the financial crisis, no one understands what's on the news. The funny thing is people have intepreted what they heart and seen in very different ways. My description of the character is types of people who pretend to care about the news, but actually he/she doesn't understand what's going on. I want to produce many reversal recognitions for audience, and to create the "ah ha, oh, he is such a character that different from what I saw him before reading what he reads and listening to what he listens to" I realized because of it is a newspaper, the contend also matters. I in fact, just want to use the form to show the non-sense, but since the content is about election, people will of course associate the theme with elections. That's another thing I should be careful. On one hand, I could take advantage of the content, and on the other hand, if I don't want people to associate with the content, I should make the paper less specific, not a new york times or so.


weather map --- 1945 / 1985 sihe garden

please click to view the bigger picture

The garden is called Sihe Garden, in Beijing. The picture above was my grandpa's parents' house, with different rooms which my grandpa, his brothers, his sisters lived. Different rooms have different conditions and could only be used by certain people, e.g. my grandpa's sisters can not live in the position where my grandpa lives. Different rooms represented how high the status was. Parents were living in the middle main room. The oldest son of the family was No.1, living in the left wing of the garden, then the second son, living in the right wing. And sisters can only live in the backyard. The weather refers to their status.

The picture below was the same house, but in 1985. The change of the society affected the use of the garden. There were different families SHARING this garden, and they were under different family names. There were no "higher, lower" statues anymore and basically, everyone was equal and the same.

In terms of the narrative, the important nformation on the corner was missed by most readers. It's better to use diferent fonts.
