A hemisphere of 5,500 white blocks occupies the air, each hanging from above in a pattern which repeats in order and disorder. Pixels play over the physical blocks as an emulsion of digital light within the physical space, producing a habitat for digital forms to exist in our world.



This is “Assembly”, the latest installation by Kimchi and Chips located in Nakdong river cultural centre gallery in Busan, Korea.
A group of external projectors penetrate the volume of cubes with pixel-rays, until every single one of the cubes becomes coated with pixels. By scanning with “structured light“, each pixel receives a set of known information, such as its absolute 3d position within the volume, and the identity of the block that it lives on.



Final systemA camera calibration app written in openFrameworks allows them to determine the intrinsics and extrinsics of the cameras following a chessboard calibration routine. This data can then be used to calibrate the projectors using structured light. They define the calibration tree as a travelling salesman problem, with different calibration routes (e.g. camera A to camera C) being assigned a cost based on the accuracy of the available calibration route, they then evaluate the best calibration tree for each camera and projector, and integrate through the calibration.

Each day a startup script first performs the scan in openFrameworks and then starts the runtime in VVVV.An application first performs the simultaneous capture of structured light on the 5 cameras whilst stepping sequentially through each projector. Following this they triangulate the projector pixels to create a dense mapping between the 2D pixels of the projector and the physical locations of those pixels in 3D space. This map is then stored to disk.

The startup script then loads VVVV which transfers the datamaps to the GPU. They define ‘brushes’ using HLSL shaders which act on the dataset. Different brushes generate different visual effects, for example, some generate density fields which are interpreted as either gradients or isosurfaces. The VVVV graph plays through a script of generative animations and performs systems management.

Kimchi and Chips is Elliot Woods (UK) and Mimi Son (South Korea), a digital media art and design practice based in Seoul which conceives and produces environments, installations and products to enable unexpected and beautiful experiences for people living today.
Their installations focus on the interactions/reactions of people when faced with new media materials, leading them to deconstruct the technical and artistic paradigms of new media techniques and develop them in novel directions.

The result is new ways of merging artificial realities into physical ones in order to create natural interactions between people and the possibilities of the digital world.
Their artistic enquiry focuses on storytelling and the sharing of memories, through which they create private and social experiences through interactions between humans and their artworks.

2012 Yeosu EXPO HYUNDAI MOTOR GROUP - Hyper-Matrix

Hyper-Matrix is a kinetic landscape installation created for the Hyundai Motor Group Exhibition Pavilion in Korea, the 2012 Yeosu EXPO site. The installation consists of a specially made huge steel construction to support thousands of stepper motors that control 320x320mm cubes that project out of the internal facade of the building.



The foam cubes are mounted to actuators that move them forward and back by the steppers, creating patterns across the three-sided display. Comprised of what at first appear to be three blank white walls, Hyper-Matrix installation quickly comes to life as thousands of individual cubic units forming a field of pixels begin to move, pulsate, and form dynamic images across the room, creating infinite number of possibilities in the vertical, 180 degree, landscape. In addition, as the boxes are arranged at only 5mm narrow intervals, the wall can also be a nice moving screen for the images projected on to it.

Hyundai Motor Group Pavilion (Intergrated Experience Hall), EXPO 2012, YEOSU, KOREA
May 12 ~ Aug 12, 2012



Jonpasang, a Seoul based media arts group, created this installation titled “Hyper-Matrix” for the Hyundai Motor Group Exhibition Pavilion in Korea, the 2012 Yeosu EXPO site.

The installation comprises a specially made steel construction to support thousands of stepper motors that control 300x300mm Lightweight blocks to move in and out of the facade, creating infiniti number of possibilities in the vertical, 180 degree, landscape.

The audience also took part in the installation as thousands of cubes start moving by the audience’s sounds. Pixel waves sweep the space, ripples emit from the centre and just in case this is not enough, projection mapping takes care of the rest.
Jonpasang collective includes Jin-Yo Mok, Sookyun Yang, Earl Park, Jin-Wook Yeo and Sang-Wook Yu.

This hypothetical device informs your quantum state within innumerable versions of our universe in the quantum state of the universe. The main idea is inspired by an equation, the measurement of existence from the relative quantum mechanics created by physicist, Everett who invented Many-World theory.

Quantum state of the universe:
| Ψ UNIVERSE 〉 = ∑αi | Ψ WORLD i 〉
Measurement of the existence:
μi ≡ 〈 Ψ UNIVERSE | Pi | Ψ UNIVERSE 〉

The theory explains that there are many worlds existing in parallel in the Universe. Although all worlds are of the same physical size (this might not be true if we take quantum gravity into account), and in every world sentient beings feel as "real" as in any other world, in some sense some worlds are larger than others. I describe this property as the measure of existence of a world. "I" also have a measure of existence. It is the sum of measures of existence of all different worlds in which I exist; equally, it can be defined as the measure of existence of my perception world. Note that I do not experience directly the measure of my existence. In the system of the parallel universe, I feel the same weight, see the same brightness, etc. irrespectively of how tiny my measure of existence might be.

The measurement of Existence is an interactive installation that incorporates both an animated graphic and sound. The device shows the simultaneity of innumerable state of a single electron forms the probability wave. As a viewer get closer and observe the ambiguous state of the electron, the device is triggered to show the next stage of the visual information of the viewer’s existence within the system of the parallel universe. In the theories of quantum physics, the acts of observation and measurement play a critical role in creating our physical reality. When it is activated by the power of observation, it examines the sensory mechanism of measurement from the viewer, such as cognition and sight. Then, it visualizes a parallel state of the viewer’s universe, from clustered groups of galaxy to the solar system the earth inhabits.
