Inverta
A circular axle is able to rotate by the use of 36 universal joints hanging from perspex rods and transmitting their rotary motion onto the next. In between the joints, 36 stainless steel objects are attached that rotate at the same speed as the axle. One of the objects has a slightly thinner body, making room for two integrated timing pulleys and thin cogged belts that connect it with the drive mechanism situated on the upper circular frame. The objects are made from thin sheet material and are carefully balanced by placing several counterweights inside their hollow bodies and by perforating their tails, reducing the amount of material furthest away from the axle. During the entire revolution their centre of gravity perfectly aligns with the position of the axle so that a stable rotation is ensured.

Trajectoir
Diese ausgewogene Skala, ein Gerät, das für die Bedürfnisse der Show hergestellt wurde, bietet eine weitere Szene. Dort niederzulassen wirft den Körper sofort in eine andere Welt. Ich war noch nie auf dieser Reise. Als Zuschauer bin ich fasziniert und ratlos. Es ist eine fremde Welt, in der man lernen muss, sich durch Erkundung zu bewegen. Kein Bodenkontakt. Das Gewicht ist immer noch da, aber die nahezu perfekte Balance des Gegengewichts ermöglicht ein müheloses vertikales Öffnen. Sie müssen nur ein Bein, einen Arm bewegen. Kaum. Die Waage ermöglicht Unbeweglichkeit in der Luft. Alle Bewegungen des Körpers drehen sich um den Punkt der Befestigung des Gleichgewichts, des Rotationszentrums, des Herzens dieser Welt.

Blasen im Canyon
Der in Paris lebende Künstler Vincent Leroy hat seine charakteristische Verwendung von schwebenden Kugeln zum Bryce Canyon in den USA verwendet. Dieses konzeptionelle Projekt mit dem Titel “Bubbles in Canyon” stellt sich eine Masse transparenter Kugeln vor, die in Rotation zwischen den Klippen hängen. Die Installation soll den Zuschauern die Möglichkeit bieten, die Natur durch einen optischen Effekt zu betrachten.

FILE FESTIVAL

At night a projection from a moving car is shone on the buildings. The car projects a video of a tiger whose movements are programmed to correspond to the speed of the car: as the car moves, the tiger runs along it speeding up and slowing down with the car, as the car stops, the tiger stops also. The framerate of the movie corresponds to the speed of the wheel rotation, picked up by a sensor. The viewers are elevated from the everyday reality through this element of fantasy into a world with more dimensions, possibilities and perhaps beauty.

ROTOЯ
The Rotor is equipped with a four channel speakersystem and a 360° camera. The artists control the speed of it’s rotation which directly influences the projected video-images as well as the sound-characteristics and the perception of the object itself. Acceleration & deceleration become main parameters, which enables the artists to compose an otherworldly piece that seems to follow it’s own logic. A strange communication between audio, video, object and light establishes itself and seduces the audience. There is the hypnotic movement of the sculpture while inevitable auditory and visual feedback is used as a central aesthetic element: The rotating speakers are amplified by static microphones, provoking complex feedback loops and patterns, that trigger psychoacoustic sensations.

The form of becoming
In this abstract system, each intelligent agent is embodied as a motor, the states in its environment is represented as an angular range of rotation and the actions as one of two directions in which each agent can move a linear actuator. Each linear system holds a segment of a long black string, this translates as a point in the represented line. Once the system runs, each agent learns, from informational equivalents of pain and pleasure, to move towards the highest values within its environment, this means ultimately to displace its position from point A to B. In order for an agent to learn, it needs time, generations of exploration, each agent will get punished for bad decisions and rewarded for appropriate ones. Every time a learning generation is finished, a light will blink for that particular agent, indicating the end of a cycle and the achievement of new knowledge; the agent becomes more intelligent. Once all agents learned to be and stay in point B, the system, as a collective, has successfully mutated into a stable, balanced, symmetric and silent form; a straight line. Finally, after a few seconds, the sculpture forgets, all agents are rebooted and the cycle of creation, chaos and order restarts, this time with a totally different and unique behavior.

Grid
Grid 4×4 is an autonomous apparatus that creates an endless series of geometric forms. The vertices of the form are located on discs, each of them rotatable by a motor. A computer software plays tenderly with the rotation of the discs and generates an endless amount of geometric and chaotic patterns.

The Kinetic Storyteller
The Kinetic Storyteller is a playful environment for social interaction consisting of a pair of swings next to each other. As participant swings on a structure, they are connected to the twitter stream of the networked landscape around them. With each kinetic swing rotation, new messages tagged with specific hashtags are presented on three large screen situated in front and to the sides of the participants.

Bubbles in Canyon
Paris-based artist, Vincent Leroy, has taken his characteristic use of levitating orbs to bryce canyon in the USA. This conceptual project, titled ‘bubbles in canyon’ imagines a mass of transparent spheres suspended in rotation between the cliffs. The installation hopes to offer viewers the opportunity to contemplate nature through an optical effect.

Internal view of the O’Neill cylinder
“One of my earliest Space Colony paintings was based on the giant ‘Model 3’ cylindrical habitats envisioned by Gerard O’Neill. I imagined the clouds forming at an ‘altitude‘ around the rotation axis. At this time the scene is bathed in the ruddy light of all the sunrises and sunsets on Earth at that moment as the colony briefly enters the Earths shadow, out at the L5 Lagrangian point where stable locations are easily maintained. Oil on canvas panel disposition unknown. “

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.

1.78 madrid
Per festeggiare i 400 anni di storia di Plaza Mayor nella capitale spagnola è comparsa, dal 9 al 19 febbraio 2018, un’opera dell’artista Janet Echelman (1966, Tampa, Florida). Il risultato è stato straordinario: un’opera d’arte, sospesa nel cielo, il cui titolo è 1.78. 1.78, è il tempo in microsecondi che, secondo gli scienziati della Nasa, rappresentano il tempo trascorso il giorno del terremoto del Giappone nel 2011, un evento sismico così potente da mutare gli equilibri terrestri accelerando la rotazione del pianeta.

Souvenir
Being self-lighted, at the same time that it rotates on its own axis, the object distorts that which it apparently seeks to represent. Therefore, the presence of an inner light, associated with the rapid movement produced by the globe’s motorization, is responsible for abstracting any border line. By fostering the internal luminosity of a planet, which is pure darkness, the work relegates the value of representation to a second level and gives rise to a set of ideas disconnected from the real. In this sense, Souvenir is a means of reconsidering in what way the demarcations that define the geopolitical scenario of this tiny globe are lost in the Earth’s infinite rotativity.

The CMS consists of an industrial robot arm with six independent axes, extended with an L-shaped cabin axis. The seventh axis allows for varying the orientation of the cabin with respect to the robot arm by changing the location of the cabin’s attachment point from behind the seat to under the seat, or any intermediate position. Recently, the CMS has been further extended with a linear axis of ten meters. The resulting eight degrees-of-freedom (DOF) provide an exceptionally large workspace. Several extreme motions and positions can be achieved, such as large lateral/longitudinal motions, sustained centrifugal motions, infinite head-centered rotation, and up-side-down motions.

transdock

TRANS-DOCK is a docking system for pin-based shape displays that expand their interaction capabilities for both the output and input. By simply interchanging the transducer modules, composed of passive mechanical structures, to be docked on a shape display, users can selectively switch between different configurations including display sizes, resolutions, and even motion modalities such as rotation, bending, and inflation.
In our paper accepted to TEI 2020, we introduce a design space consisting of several mechanical elements and enabled interaction capabilities. Our proof-of-concept prototype explores the development of the docking system based on our previously developed 10 x 5 shape display, inFORCE. A number of transducer examples are shown to demonstrate the range of interactivity and application space achieved with the approach of TRANS-DOCK.

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.

Yuca easy chair
It looks like a spatial sculpture, at once experimental and inviting, rotatable and completely covered. The YUCA easy chair is reminiscent of a softly rounded cup of petals, appearing to grow out of thin air. It stands on a metal X-shaped base which is chrome-plated or lacquered. The result is a perfect shape brimming with flexibility and seating comfort.

timeLandscape woolrhythms

“timeLandscape – wool rhythms” 2010. Part of timeLandscape series, 2009 – 2010. Video, audio, projector, speakers, custom patch (PD-Gem), sensor, wool engine. Variable dimensions and duration, loop. “timeLandscape – woolrhythms” is an interactive audiovisual installation in which a landscape is depicted from its multiple time possibilities and [re]composed through users’ real time interaction. The installation was developed in Biella, Italy, an area economically attached to textile industry, and deals with the cyclical perception of time and human, linear, interference on it. It gathers nature and artefact, by connecting a physical wool engine to digital imagery of daily cycles. By turning the wheel crank, users generate movement starting the engine. Through a sensor attached to the machine, software calculates the rotation speed, altering parameters for mixing audio and video fragments in real time. Every turn of the machine leads to different time thread combinations in response to the rhythm and speed of each interactor.

Cubic Limit
In «Cubic Limit,» Mohr introduces the cube into his work as a fixed system with which signs are generated. In the first part of this work phase (1972–75), an alphabet of signs is created from the twelve lines of a cube. In some works, statistics and rotation are used in the algorithm to generate signs. In others, combinatorial, logical and additive operators generate the global and local structures of the images.

Pebble
The ‘pebble’, conceived by vincent leroy, occupies a space with an incredible aesthetic experience. This gigantic elliptical mirror floats with utmost grace, softness and voluptuousness, like this example inside the ‘grand palais’ in paris. The installation forms a sensory experience rather than a visual one. With the mirrored effect, the ground and horizon move slowly until they disappear, making you lose your mark. French artist vincent leroy slows down time and displays his magical mechanism, using the same technology as his boreal halo: inflatable with steel cables in slow rotation.

Symmetryscope
Experimental project SYMMETRYSCOPE tryes get to the bottom of symmetry and reveal its possibilities. At first step the liner symmetry was investigated and several columns were made. The principle consisted in the rotation and mirroring geometrically simple shapes (tetrahedron). However, the geometry of the column did not allow any internal spaces and so were unusable for architectural purposes. Another move forward was done by the planar symmetry. The principle was similar to the columns. The effort was to achieve interior spaces.

Heaven’s Carousel
Mit dem »Heaven’s Carousel« scheint im Herzen der Karlsruher Innenstadt vor dem Naturkundemuseum ein leuchtendes Klang-UFO gelandet zu sein, das antike Sphärenmusik unter den Vorzeichen der Astrophysik des 21. Jahrhunderts neu interpretiert.In zehn Metern Höhe schwebt an einem Kran eine luftige Karussell-Konstruktion, von der an zwölf Strängen insgesamt 36 kugelförmige, leuchtende Lautsprecher hängen. Das »Heaven’s Carousel« hebt in den Abendstunden ab: In Rotation versetzt, drehen sich die in Leuchtkugeln integrierten Lautsprecher mit einem Durchmesser von bis zu 16 Metern über den Köpfen der BesucherInnen. Sie sind eingeladen, sich unter der Installation frei zu bewegen, um das sich kontinuierlich verändernde Klanguniversum zu erkunden. Auch wenn aus den einzelnen Lautsprechern »nur« reine Töne erklingen, so rekombinieren sich diese im Raum zu komplexen Klanggebilden. Aufgrund des Doppler-Effekts klingt dabei ein Ton höher, wenn die Klangquelle auf die BesucherInnen zufliegt, und tiefer, wenn sie sich wieder entfernt.Die Illumination der Lautsprecher vervollständigt das als Auftragsarbeit der Europäischen Raumfahrtagentur (ESA) für das Hubble Space Telescope entstandene Gesamtkunstwerk. Die Helligkeit zeigt nicht nur die relative Lautstärke und Aktivität einer Klangkugel an, sondern die gespielte Tonhöhe wird auch in eine spektrale Farbe übersetzt.

tour en l’air
With “tour en l’air”, the Berlin artist Ursula Neugebauer returns to an unforgettable childhood experience: Donned with the first long skirt in the fast turn around your own axis, to experience a previously unknown body feeling – and to get to know a new form of stability in the rotation.
Tour en l’air is an impressive installation at the intersection of fashion, art and architecture. Decorative busts slip into several floor-length red taffeta dresses and come to life thanks to computer-controlled electric motors. Although the individual components are of purely mechanical and material origin, the overall composition appears as a poetic expression of the human: namely a magical dance.

Соединяется как очень четкая мысль. В результате получается коммутатор, который определяет разные уровни, создает структуры и определяет отношения, которые позволяют определенную степень ориентации ». (Даниэль Бауманн)

Digits
File Festival
“Digits” is a single player wall projection installation game using a multi-touch tablet (iPad) as a controller. The game consists of moving a puppet using a set of dials.
The player can manipulate the dials on the tablet by performing a rotational gesture with the finger, which will rotate the joints of the puppet on the wall projection. Multiple dials can be rotated at the same time.
If the player lifts his fingers from the touch screen, the joints and limbs of the puppet will gradually fade and loosen his articulations. Because the puppet is subject to gravity, the player has to time the joint rotations in order to coordinate the movements of the puppet.

CYCLOID-E

This piece, which comprises a series of tubular pieces arranged horizontally and activated by a motor, generates a particular sound through its movement, which is unexpectedly harmonic. The artists have taken their interest in the mechanisms that generate wave motions as a starting point to create this sculpture: five metal tubes joined together feature sound sources and sensors that allow them to emit different sounds based on their rotations.
The sculpture runs through a series of rhythmic movements, like a dance, creating, in the words of the artists themselves, “a unique kinetic and polyphonic work, in the likeness of the “Cosmic Ballet” to which the physicist Johannes Kepler refers to in his “Music of the Spheres” in 1619.” This work is part of the reflection on the possible interactions between sound and movement developed by the artists since 1999, using electronic devices and inspired by the aesthetics of industrial machinery.

Eartha

Eartha, the world’s largest rotating and revolving globe, is located within the headquarters of the DeLorme mapping corporation in Yarmouth, Maine. The globe weighs approximately 5,600 pounds (2,500 kg), and has a diameter of over 41 feet (12.5 m). This gives it a scale of 1:1,000,000, on which one inch represents 16 miles (26 km), one millimeter represents one kilometer. As with most globes, it’s mounted at a 23.5 degree angle, the same axial tilt as the Earth itself; thus the equator is diagonal to the floor. It uses a cantilever mount with two motors, and simulates one day’s revolution and rotation every hour, though it is possible for the motors to fully rotate the globe in as little as one minute.
