HYPER FRACTAL

When I was a child I had some vivid dreams. They felt like I was falling and flying into an infinite multi-dimensional environment. They were satisfying and terrifying at the same time but I couldn’t find any explanation for them. 6 years ago I read about Benoit Mandelbrot’s theory, the fractals, and it changed my perspective. I realized that my dreams were fractals. So I tried to remake my dreams as a visual VR experience. According to Benoit Mandelbrot’s theory, Fractals are the mathematical\visual explanation of the nature’s structural geometry. Geometry for irregularity.

Blueprint

Blueprint embraces the relationship and parallels between art and science, creating compositions through the mathematical principles of logic that underpin life. Exploring analogies between DNA and computer code, UVA have created the Blueprint series; works that pair genetics and code as the blueprints of artificial and natural systems. As the work slowly changes over time, patterns fluctuate between varying degrees of complexity. Blueprint uses the basic concepts of evolution to create an ever-transitioning image. With cells literally transferring their genes to their adjoining others, colour flows like paint across the canvas. Drawing up a unique colourful composition every minute, Blueprint presents the unlimited outcome that results from a single algorithm; a single set of rules.

Antrum

The installation looks like a grotto of the membrane, the surface of which is inhabited by strange creatures. It’s complex structure causes association with living creatures, space objects and architectural constructions. In this frontier word pure mathematical abstractions are mixed with natural shapes, resulting in formation of new entities. Viewers can push the membrane and try to contact with them.

the concept of … (here and now)

In front of a giant screen, two dancers interact with a cohort of cameras… Their movements are captured by infra-red sensors and projected onto the screen, whereby their bodies become the canvas on which new images take shape. The result is a shifting kaleidoscope of strange, living, quasi-mathematical visual worlds which sometimes seem to be emanating or even escaping from the dancers’ bodies. “Who decides which movement to make: the man or the machine?” Blurring the line between the real and the virtual, Klaus Obermaier loves to subsume his performers’ bodies and physicality in a disconcerting digital universe. With his latest creation, the choreographer/artist has taken a bold new step. He has constructed a system of projectors and infra-red sensor-cameras, trained upon the movements of two dancers. The performers thus find themselves thrown headlong into a living, moving graphical universe: their movements are projected onto the screen, but at the same time their bodies are illuminated by more projected images. This is a true artistic performance, pushing well beyond the frontiers of a standard dance recital, or even a contemporary dance show. A corporeal, temporal performance. A choreography which makes subtle use of its raw materials, deftly combining lights, video, perspectives and the real-time power of bodily movement.

THE TRANSPARENCY OF RANDOMNESS

“The Transparency of Randomness” gives insight into the world of randomness. In this interactive installation, visitors can directly experience the significance of the complex interplay of randomness and stochastics in current mathematical and physical research. 27 transparent boxes, floating in space, continuously generate random numbers by using the well-known medium of the dice.The process of random number generation is influenced by the complexity of nature and its structures, using a variety of natural materials. The ensemble of all generated random numbers forms the basis of a real-time calculation and comprehensibly demonstrates the impressive role in scientific research.

Flatsun

A circular display that simulates the turbulence at the surface of the Sun using mathematical equations. The piece reacts to the presence of the public by varying the speed and type of animation displayed. If no one is in front of the piece the turbulence slows down and eventually turns off. As the built-in camera detects people more solar flares are generated and the fake Sun shows more perturbation and activity. At 140 cm diameter, Flatsun is exactly a billion times smaller than the real Sun. The piece consists of custom-made panels with 60,000 red and yellow LED lights, a computer with 8 processing cores, a camera with a pinhole lens and a mechanically engineered aluminium, steel and glass structure that pivots for maintenance. A single knob lets the collector set the brightness of the piece and turn it on and off.

Datum

Any pixel in a digital movie file can be described as a point in 6-dimensional Euclidean space [x,y,R,G,B,t]. the rotations in 6-dimensioal space converts curve in form to gradation in colour, colour to motion in time axis, motion to curve and curve to colour. relations beween all of pixels are mathematically conserved through the conversion.

this visual object is “mathematically” digital colour movie data itself as sequence of numbers. it’s a nature of data.

Licht, mehr Licht!

“Licht, mehr Licht!”, or “Light, more light!” in English, were the great German author and scientific thinker Goethe’s dying words. The installation, created and developed by French visual artist Guillaume Marmin, echoes near-death experiences, whose survivors describe a “tunnel of light” opening up beyond the darkness. Marmin’s works give form to the intangible, unveiling the beauty of the unseen and the mathematical foundations of reality.

superposition**

superposition is a project about the way we understand the reality of nature on an atomic scale and is inspired by the mathematical notions of quantum mechanics. Performers will appear in his piece for the first time, performing as operator/conductor/observer/examiners. All the components on stage will be in a state of superposition; sound, visuals, physical phenomena, mathematical concepts, human behaviour and randomness – these will be constantly orchestrated and de-orchestrated simultaneously in a single performance piece.

Möbius Ship**

The ambitious and imaginative structure of Hawkinson’s sculpture offers an uncanny visual metaphor for Melville’s epic tale, which is often considered the ultimate American novel. Möbius Ship also humorously refers to the mathematical concept of the Möbius Strip. Named after a nineteenth-century astronomer and mathematician, the Möbius Strip is a surface that has only one side, and exists as a continuous curve. Its simple yet complex spatial configuration presents a visual puzzle that parallels Hawkinson’s transformation of the mundane materials into something unexpected.

‘Tempo: cor’(Time:color) consists of an immersive installation that seeks to modify our experience of time by converting hours into color. A set of chromatic clocks, each set to a different GMT time zone, projects, in a semicircle, the current time in their mathematical and chromatic representations. The conversion between these two forms of time representation is based on an algorithm composed of sinusoidal functions that modulates the RGB colors as a function of the current time, gradually modifying the intensities of blue, green and red throughout the day: at midday yellow predominates, while at four in the afternoon the hour is red; midnight is blue, six o’clock in the morning is green. Side by side, the colors projected by the clocks merge, creating an immersive experience of a continuous and circular time, between the different time zones, that crosses the entire chromatic spectrum. This installation is part of a series of works in which I investigate the relationships between human notations and codes and our experience of space-time, seeking to change the ways we understand it; in this case, visitors immerse themselves in a spatial experience of time that provokes the questioning of notations and perceptions that we usually consider axiomatic. Changing the way we represent time will change our way of experiencing it?

**Pow2045**

The mathematical construct covers the human body, yet sets a contrast to organic shapes in its accuracy and mechanical precision. This kind of visual contrast can be understood as a visual representation of human computer difference and reveals core features of both – man and machine. A characteristic foundation to design the dialogue of “POW 2045″

**Discrete Figures**

‘Discrete Figures’ unites the performing arts and mathematics in a dramatic exploration of the relationship between the human body and computer generated movement (simulated bodies) born from mathematical analysis. As an additional layer of complexity, the performance piece utilizes drones, A.I., and machine learning in the quest for a new palette of movement to foster undiscovered modes of expressive dance that transcend the limits of conventional human subjectivity and emotional expression.

The Geometry of Musical Rhythm: What Makes a “Good” Rhythm Good? ” is a book on the mathematics of rhythms and drum beats. It was written by Godfried Toussaint, in order to study rhythms mathematically, Toussaint abstracts away many of their features that are important musically, involving the sounds or strengths of the individual beats, the phasing of the beats, hierarchically-structured rhythms, or the possibility of music that changes from one rhythm to another. The information that remains describes the beats of each bar (an evenly-spaced cyclic sequence of times) as being either on-beats (times at which a beat is emphasized in the musical performance) or off-beats (times at which it is skipped or performed only weakly). This can be represented combinatorially as a necklace, an equivalence class of binary sequences under rotations, with true binary values representing on-beats and false representing off-beats.

Data-verse

Ryoji Ikeda’s new trilogy data-verse, commissioned by Audemars Piguet, is an audiovisual symphonic suite that attempts to encompass the tiniest (elementary particles) to the greatest (Universe) scale in Nature.Data-verse is the ultimate chapter of Ikeda’s audiovisual series that first began in 2000, which focuses on his own data-driven research and aesthetics.Through his mathematical composition and aesthetics, massive scientific data set will be processed, transcribed, converted, transformed, de/re/meta-constructed and orchestrated to visualize and sonify the different dimensions that co-exist in our world between the visible and the invisible.

**Captives**

Captives is an ongoing series of digital and physical sculptures by Quayola and a contemporary homage to Michelangelo’s unfinished series “Prigioni” (1513-1534) and his technique of “non-finito”. The project explores tensions and equilibrium between form and matter, man-made objects of perfection and complex, chaotic forms of nature. In this series mathematical functions and processes describe computer-generated geological formations, endlessly evolving and morphing into classical figures resulting into life-size ‘unfinished’ sculptures.

“Vantongerloo, who ascribes to the abstract language of form after 1917, applies himself to Abstract Art in order to get control of rules by which he develops an interest in geometrical relationships and algebraic formulas. In addition to his artistic practice, Vantongerloo also writes theoretical work about his research. Primarily after the publication of his pamphlet L’Art et son Avenir in 1924, he creates new impulses for geometric abstraction with his writings. In this way, for example, he subjects three neo-plastic works of Piet Mondriaan (1872 – 1944) to an analysis in the French publication Vouloir. In this way he opens up the way for his own ‘mathematical’ abstraction.” Sergio Servellón

Abraham Palatnik

Kinechromatic

His “Kinechromatic Machine” series, first exhibited at the inaugural São Paulo Biennale in 1951, earned him an official award while creating a stir among the judges uncertain on how to classify the novel art form.From 1964 onwards, he developed the Kinetic Objects, an unfolding of the kinechromatics, showing the internal mechanism of operation and suppressing the projection of light. Mathematical rigor is a constant in his work, acting as an important resource for ordering space. He is internationally considered one of the pioneers of kinetic art.

Nature Abstraction

Nature Abstraction is an immersive sensory experience that explores the arcane forms of fractals, mathematical visual representation of natural and biological forms.

The project gives an insight of their aspects through virtual reality, where they appear as three planets: Birth, Communion and Aether; Each accompained with scores designed to facilitate meditative state and relaxation;The audience is guided to explore these planets and dive into their vast complexities as well as observing the contrast between the entirely digital created world inside the VR against the fully analogue created film projected onto the faces of the cube which have been filmed in real life, recreating using analogue visual effects and various chemical elements.

**THE DOG DAYS ARE OVER**

THE DOG DAYS ARE OVER will be a work that tries to reveal the person behind the dancer. To reach this, a very complex, mathematical, dynamic and tiring choreography is constructed, which is performed almost completely in unison. The difficulty degree of the choreography is so high, that the dancers eventually will go wrong. It is there where the mask falls. The dancer is defined as an idle and purely executing species, striving for perfection.

**88.5° Arc x 8**

Bernar Venet is a French Conceptual artist known for his curved, mathematically precise metal sculptures, and for his material exploration of coal, asphalt, and tar. “My work is self-generated. Nothing around me serves as a particular inspiration,” Venet said of his art. “I work, and I make discoveries while remaining open-minded to anything that might present a new possibility in the context of my work; this framework looks to enlarge its scope as a result of new formal and conceptual discoveries.” Born on April 20, 1941 in Château-Arnoux-Saint-Auban, the painter and sculptor studied at La Villa Thiole in Nice in 1958 for a year before pursuing a career as an artist. Friends with Arman, Jean Tinguely, Donald Judd, and Sol LeWitt, Venet worked within Minimalist and Conceptualist modes during the 1960s and 1970s.

Vielecke und Vielfläche

Regular convex polyhedra, frequently referenced as “Platonic” solids, are featured prominently in the philosophy of Plato, who spoke about them, rather intuitively, in association to the four classical elements (earth, wind, fire, water… plus ether). However, it was Euclid who actually provided a mathematical description of each solid and found the ratio of the diameter of the circumscribed sphere to the length of the edge and argued that there are no further convex polyhedra than those 5: tetrahedron, hexahedron (also known as the cube), octahedron, dodecahedron and icosahedron.

Field and Loops

Loops and Fields, is a collection of drawings that resonate sympathetically to the electromagnetic fields within the gallery. These graphite drawings function as graphic antennas and explore the qualities and inherent nature of a combination of hand-drawn and mathematically generated forms. Delving into algorithmic structures, fractals and the chaotic nature of the hand drawn line, these drawings are an exploration of conductive materials and the possibilities for drawing electronic components. When connected to a sound system they make audible their interior activity and reveal the energy that exists in the immediate environment.Relying on the basic principles of the directional loop antenna, the drawings in Loops and Fields, like any receiving antenna, convert an electromagnetic wave into a voltage; the loop antenna is particularly sensitive to magnetic fields and outputs a voltage proportional to that field. Monitoring this activity allows us to experience the local fields and generates a site-specific and dynamic aural landscape.The different shapes and line qualities that make up the algorithmically generated and stencilled drawings come from thinking about the possibilities of extending a line. Fractal mathematics and the research into fractal antennas has focused on reducing the overall size and space an antenna needs to occupy. My interest is in the frequency range at the lower regions of the spectrum, where the wavelength is large; so my interpretation of recent antenna design research has led me to explore the possibilities for drawing antennas that can receive large wavelengths, on something the size of a standard piece of fine art paper.

Marionettes

FILE FESTIVAL

“Marionettes” is a seven-minute computer animation about collapse. Marionettes are controlled by strings: if there is no string, they collapse. Nobody animates the body. If nobody animates the body, it will be animated by natural forces. Mass. Gravity. Collision. Randomization. In this animation, the animator does not animate in traditional terms. Thus, we might say it is an anti-animation.

The forces that control the movements of the marionettes are calculated by physical simulation algorithms. Therefore, these movements are strictly mathematical ones. They are dramatic, too. They visualize collapse in its physical and – amazingly enough from puppets animated by machines – psychological sense.

After his PhD, the world of the “dot-com” internet boom was more appealing than academia, so Tom became a web developer specializing in e-commerce content management systems. For the past ten years Tom has worked at a variety of agencies in Scotland and now currently works at Glasgow based 55 Degrees, which specializes in interactive museum exhibits and video production. Tom considers himself to be a ‘creative coder,’ a techie who also has an appreciation for the aesthetics. His site, subblue.com, is where he writes programs and plugins exploring mathematical and generative graphics. Where possible, these experiments are interactive and have the source-code available for download. The exposure of his site and the Photoshop and After Effects plugins he has released have resulted in the creation of book covers, music videos, and stage visuals.
