the way things go by TK from italy

The Way Things Go is a freestanding design bookcase conceived as a contemporary architectonic structure. Five sinuous elements mirror one another as if a sudden gust of wind had reshaped their minimalist lines, while triangles of metal tubing are used to join and support the carbon fibre shelves. The result is a natural movement where the bookcase’s weight and epicentre continuously shift to magically create a modulated effect of irregular motion in an erroneously precarious equilibrium. The dual-sided bookcase can be used as a room divider.
The slightly curvaceous design produces a light, good-looking and functional shelving structure whose natural composition gives life to an elegant and original aesthetic. The Way Things Go can be customised for different environments during the design phase.
A dynamic composition of 30 shelves assembled with 50 metallic structures melds experimentation and research to create unique pieces. A wealth of features and details generated in a technically precise and sophisticated manner using the computer give the project a completely natural and fluid appearance.
Current technology enables design to harness an infinite universe of options and, paradoxically, brings the designer closer to nature’s world of perfect forms.
Technical explanation
This project is to realize a bookshelf which changes its shape according to a (MOTION) simulated by programming techniques.
Firstly, I have created a basic unit that can be reformed by numeric input.
I have prepared a function which can decide details of requested component parts. The size and thickness of each component parts can be edited by numerical input.
Also the whole proportion and inclination are adjustable by a function.
The data of coordinate points of 5 bookshelves put in a straight line is input to the physical simulation program and a motion like the flag fluttering is reproduced by wind simulation.
The direction of a wind, gravity and their strength can be edited by parametric inputs.
Simulation is stopped in arbitrary moment and the data of coordinate points is extracted.
The basic four points which should become a shelf board are chosen considering the order of the coordinate points.
However, the rectangle plane which consists of four points of arbitrary positions might be awry, so it will be needed to run an operation for planarization.
When the planarization is completed, the normal vector of each shelf board is extracted, and the program begins to create continuously the vector which gives the thickness of a shelf board constructing the basic lines of structure forms, which creates the basic unit to optimize the relation of the components.
The balance of center-of-gravity will be adjusted by function, which makes structure become thin and makes depth of a shelf board narrow adjusting a twist of the whole structure.
Since these simulation work in parallel, infinity combination is possible according to quantity of basic units, i.e., the whole length , and the quantity of shelf board of each unit.

Materials
Since center-of-gravity balance is important, a light and hard thing is desirable. 
A shelf board, made of an aluminum alloy or carbon fiber sheet.
Structure in aluminum alloy or titanium, etc. 
Although in steel it is also possible, it is hard to maintain center-of-gravity balance. 

Manufacturing process 
The data is converted into general-purpose 3D data when physical simulation is finished.
And the data required for processing of each component can be exported with identification number.

Exhibition plan 
A place of about 4 meters in length about 12 meters depth is required.
It is desirable to be exhibited in silence so that a lively motion of the shelf may be conspicuous. 
If it is possible, the shelf shall be soaked in water up to the level of the bottom line.
Creating the silence in this way may be able to make the water have the role of a fence to prevent people from closing carelessly to ensure the safety of the exhibition.
