A sequence of photographs, the process of a water drop falling into a water pool From top-left is a sequence of photos describing the process of a water drop falling into a water pool, sinking and then rebouncing. I dropped a water drop of 15Îźl (15/1000 ml) from 18cm above the water suface and took a sequence of photos using a high speed camera (taking more than 1000 photos per second) from lateral view, picking out a series of 12 photos that can best describe the whole process of a single water drop falling into water pool. This is a science research that cost me a whole year to reach the final result. Later in my life, I found that the fascinating images of this successive sequence pose a strong influence to me.

Five Water Drops on The Roof Five personal studios and five additional functions on top of a dormitory building High above the ground on the roof top of a dormitory, I found a semiopen-public space composed of some neighboring rooftop level of which people on the roof top revealed only their upper body. With this project, I create fully-focused studios and a rooftop common room for the dormitory while responding the upper-half-revealed neighbors at the same time. Yi-Ting Wei, Personal Project, 05/2013

A certain moment while a drop falling into a water pool The genesis of this project was inspired by this specific image, occured while a drop falling into a water pool, forming a space that is of solitude and concentration for me.


The prototype of the studio A personal studio of solitude and concentration

The genesis

Solitude, concentration

This image of a drop falls into water pool draws my attention due to its unique space. The space illustrates solitude, inside which man feel solitude without interruption from outside, allowing fully concentrated.

The prototype

The first form of the studio

The prototype model, made by copper wire and silk sock, demonstrates the shape of my initial concept of the space. The first form of studio is transformed to a tube of rectangular section with shallower section at the bottom.

Desending into the studio, step by step becoming fully concentrated

Looking up

People enter this studio from the top of it, where the section is wider, and then slowly descend to the lower part of this space, of which the section becomes narrower. During the process of descending, a person is step by step away from the outside world and become calmer, being ready to concentrate on his own work in this studio.

A view of sky at the top, the only connection with outside for people inside the studio.

The site condition

The site and the neighborhoods with revealing upper half bodies

semi-outdoor public spaces above the ground Due to the humid weather of my country, residents often put on a half-cut steel roof above the original rooftops of buildings in order to prevent leaking of rain water, heat of the sun creating a semi-outdoor space with good ventilation on original rooftop level at the same time. The attic of the dormitory, together with other similar semi-outdoor attics of other nearby buildings make a large scale semi-outdoor public space high above the ground.

The site of studios and the nearby five buildings with half-cut roof together make up a large semi-open public space.

The site of the studio is covered with a half-cut steel roof.

A person at the site can watch residents in the neighborhood within this semi-open public space. There is a interesting picture I observed: a resident on nearby attic, yet only with his upper half body reveals due to the short wall of the attic.

Five Drops, Five Studio Types, And Five People

Bring light and air into studio and respond the revealing upper half bodies of neighbors

Five studios are designed for five type of people: botanists, artists, fashion designers, music producers and meditation people. Each studio is opened with different height at its lower part, according to the demand of specific activity inside. The sizes of slab of each studio are then determined according to visible area of people inside the studio.

Upper and lower half body To respond the interesting picture that only upper half of neighbors' bodies are revealed, I open the lower part of the studio, bringing the lower part of the person inside studio revealed.

Extended slabs block the visibility from outside world, satisfying the initial concept of concentration and solitude while opening lower part of studios.



Fashion Designer

Music Producer

Meditation People

Botanists could do their research on plants inside this studio. The opening of this studio is relatively bigger so that plants could obtain enough sunlight from and air from outside.

Artists could do their own creative works inside this studio. The opening of this studio allow people outside the studio to see parts of the canvas and the unfinished paintings.

Fashion designers could do their own design inside this studio. The moderate size of opening prevents interruption from outside, yet people outside can see some fabric of the design.

Music producers could create music inside, of which the opening is rather small with only producer's feet reveal-ing, allowing outside to watch beating time on music of producer's feet.

People enjoy meditation could meditate inside this space. The tiny opening almost prevent all possible interference , yet provide enough sunlight and air from the bottom of the space.


Create The Five Function by Slabs

The site is located at the attic of a student dormitory. By making use of edges of slabs and adjusting the slab to proper height, five functions for students' public use are created cleverly. The desired but missing funciton of this dormitory building

Private space and private space, studios and common room

Some functions that are essential for students and expected to located in somewhere inside this dormitory building are however absent. It is now a crowded dormitory fulled of suites with no enough public space.

As the studios being a private space for workers, the other part of the space is designed as a public space, adding the five missing functions for this dormitory building by properly control the height of studios' slabs.

Study the required heights for the adding five functions. There is an essential element for each adding function, such as chair and table. I studied the proper heights for these elements. By setting the height of studios' slab according to the study, the margins of five large slabs then provide the adding five functions. Moreover, the people inside studios would not be interrupted with careful analyze of visible area by controlling sizes of slabs.


Open A Tiny Window

Open a tiny window at the side of the studio, allowing the worker to gain a little connection with outside world. Make the lower-half revealing worker inside the studio watch one of upper-half-revealing neighbors while a neighbors walking into the worker's tiny window.

Five Direction of Vision, Five Studios and Five Funtions for Public Use

Obtain the directions of five surrounding buildings with semi-outdoor attics from the map. Each studio is arranged to open a tiny window toward one of these surrounding buildings.

Five colors Each color represent a specific type studio and functions of public space creating by its slab.

Dripping, Flowing, Whirling Express the emotions of rainy days and motions of fluid by experiment the possibilities of ink, styrofoam and plaster.

This project was inspired by those rainy days with small or heavy, intense or loose rain drops falling on different surfaces in the city. Those rainy days are of different emotions but the same theme, similar as a set of variations Personal Project, 08/2013

The motions of fluid in rainy days The genesis of this project was inspired by emotions in rainy days, like a set of variations, as well as motions of fluid in rainy days: dripping, flowing and whirling.


Stamping: Dots of Ink on The Canvas

Emotions of Rainy Day: Goldberg Variations

Days of rain make me think of the wonder of music. Scenes of rainy days compose a set of variations: various emotions from one section to another with the same theme.

Every knock on the piano creat a crisp and clear sound of music, just like every drop falling on earth and every dot of ink dancing on the canvas with rhythm and emotion.

Goldberg Variations by Glenn Gould Motions of fluid I observe various motions of fluid in rainy days: mainly dripping, flowing and whirling.

To me, the sound of piano is like the motion of raindrop. I choose Goldberg Variations played by Glenn Gould, considering this a brilliant description for scenes in rainy days.



Different section of Goldberg Variations describe various scenes in rainy days.


Goldberg Variations


Sequent colors indicate a sequence of painting process according to the sequent section of Goldberg Variations. A single color represents the pitch, rhythm and emotion of a section in Variations.

Scenes of rainy days and sections of Gouldberg Variation

The various and abundant emotions of rain

Scenes from small to heavy rain, with intense or loose rain drops falling on different surfaces as well as running car or foot in rainy days tell stories with different emotions and rhythms. Specific sections in Goldberg Variations with sad, heavy, cheerful or gentle emotion describe these particular scenes.

Each section in Variation was interpreted by dots of different sizes and distribution. All sections together compose my drawing of Goldberg Variation, depicting days of rains.




Use ink splashing on the canvas to express the falling of rain drops.

Moisten a glass ball with ink, and then roll it on the canvas.

Thirty times of dipping, falling and rolling a glass ball Splash heavily or gently with full or a little ink Splash in almost similar direction, creating lines of ink drops. The sizes of drops are controlled by the amount of ink being dipped on brush and the speed of splashing.

Dip the glass ball with ink and fall the glass ball on the top-right part of canvas. Roll the glass ball by inclining the canvas until no ink remained on the ball. Reapt dipping, dropping and rolling ball for thirty times to interpret thirty sections of Variations.

There are branches spread from a drop in microscopic view of ink drop by splashing,

Traces of ink are not totally saturated due to the glass ball being out of ink after rolling a distance.

Rolling Splashing What happens while splashing ink on canvas in quiet similar to what happens while sky falls a heavy rain on the ground. The drawing which composes of numerous, tiny ink drops falling on the canvas is similar to a record of how rain drops fall on the ground.

The motion of dripping and flowing can be imitated by dropping and rolling a glass ball moistened with ink. Motions of glass ball are controlled by inclining the canvas, rolling slow or fast, straight or winding. Thirty times of operations composes another interpretation of Goldberg Variations and emotions of rains.




Drip ink drops on the canvas, and then spin the canvas, flowing the ink by eccentric force.

Fall drops of ink on the canvas, then incline the canvas, flowing the ink by gravity.

Dripping and spinning

Flow the ink vertically and horizontally

Drip the ink, some of small drops and others of bigger drops, at center area of the canvas, and then spin the canvas rapidly. The ink drops are dragged to the edge of canvas by eccentric force.

Drip the ink at one side of the canvas and flow the ink drops to the opposite side by inclining the canvas. Then drip the ink on another side of canvas flow the ink drops again. After that, fill some of the closed rectangular.

Every flow starts with a round dot, flow straight down. The horizontal ink flow, which flows after the vertical one, can be trapped by ink of horizontal flow due to the surface tension of ink.

In the micro view, the eccentric force of spinning drags the ink flow toward the edge of canvas. Each sharp turn of ink flow indicate another beginning of spinning.

Flowing Spinning Operation of spinning is a imitation of dripping and whirling of rainy days. The ink drops are dragged toward the edge of canvas by eccentric force The closer to the edge, the thinner the ink flows become, with some flow splitting to branches. All the ink flows together form a shape similar to a whirl.

Operation of flowing is a imitation of dripping and flowing of rainy days. The ink drops are dragged downwards by gravity force. The effect of surface tension can be observed while the intersecting of horizontal flow and vertical flow, horizontal one being trapped by vertical one. Also, I intentionally fill some area enclosed by ink flow, making the drawing gain some sense of rhythm.


Interpertation: Emotions And Motions of Rains and Goldberg Variations I use dripping, flowing and spinning, to creat the emotions and motions of rains and Goldberg Variations section by section.

Motions of fluid: dripping, flowing and whirling

This drawing use several operation I tried before: dots plotting, flowing and spinning.

Sequence of photos during creating of this drawing

Spinning This drawing was operated section by section according to my feeling of rhythm and emotions while listening to each section of Goldberg Variations. In some sections merely dripping is used, while in most of other sections flowing or spinning are used. Operations of the later sections often interact and cover a little operation of the earlier sections. The colored drawing on the right indicates the area of each operation with a particular color.


Goldberg Variations


Motions and emotions of rains and Goldberg Variations After several trials including stamping, splashing, dripping, rolling, spinning and flowing, I decide to use dripping, flowing, spinning to illustrate my feelings of rainy days. Each color of this drawing present the feeling of one section of Goldberg Variations, using motions of liquid I observed in rainy days. Sections interacting one another, all together compose this picture, just like various scenes composing a rainy day and sections composing Goldberg Variations. I want to present the quick and slow motions of fluid as well as depressed and cheerful emotions of music.

Different Sections of the picture: Diverse Emotions Each section expresses different emotion. Some sections with only dots tell the heavy beat of music while other sections with flowing and spinning present the vigor of music. The wider ink blot indicate the lowpitched of music as the thinner ink blot indicate the high-pitched one.


Dripping, Flowing, Whirling ─ Trails of Space Experiments of Space, Reinterpretations of Drawings trial #1 Mixing Plaster with Wax trial #2 Dissolve Styrofoam with Acetone


Trial #1 Mixing Plaster with Wax Mixing liquid wax with liquid plaster, and then stiring the mixing liquid to create the space that is full of motions like fluid.


Interpert motions of fluid: flowing, whirling I tried to interpret motions of fluid: flowing and whirling into a space form, refering to the scenes of rainy days and drawings I have done before.


Solid and empty space trial A

plaster as ink (solid space) wax as canvas (empty space)

Ink within canvas

Plaster within wax

Relationship between drawing and space: empty and solid Transform the ink drawing in to a space, express ink and canvas with plaster, and wax. The ink can be considered as the solid part in a space as the rest of canvas can be considered as the empty part in a space. In the process of creating this model, I melt the wax out of the cube, leaving only solid plaster remained. The space that wax originally occupied is empty space, and the plaster form the solid space of this cube.

Melt wax and pour the liquid wax in to a box

Mix plaster powder with water and pour in the box

Stir the liquid of wax and plaster, and then wait until wax and plaster become solid.

Put the cube inside boiling water, melt the wax out of the cube

Process: mixing plaster with wax

trial B

Mixing plaster with wax, one with property solidifying after mixing powder with water and the other with property of transforming from liquid to solid while temperature, could solidify the motions of liquid.

Two trials Mixing plaster with cold or hot water creates different textures.


A Solid Texture with Motion of Fluid

Melt the wax out of the cube, the remaining plaster record and present the motions during mixing and stirring the two liquid.

Trial A

Trial B

Mixing plaster with cold water creates a smoothe texture.

Mixing plaster with hot water creates a rougher texture.


Trial #2 Dissolve Styrofoam With Acetone

Dissolve Styrofoam with acetone, creating a unique pattern and several large or tiny room.

Solid and empty space


Styrofoam as Canvas (Solid space)

Acetone as Ink (empty space)

Interpert motions of fluid: dripping, flowing

Relationship between drawing and space: empty and solid

Styrofoam dissolve with Acetone

Transform the ink drawing in to a space, express ink and canvas with acetone and styrofoam. The relation is opposite to trial#1. The ink can be considered as the empty part in a space as the rest of canvas can be considered as the solid part in a space. In the process of creating this model, I dissolve styrofoam using acetone, creating empty space within solid styrofoam.

I tried to interpret motions of fluid: dripping and flowing into a space form, refering to the scenes of rainy days and drawings I have done before.

Ripples and the sea of umbrellas I am always fascinated by scenes of the sea of umbrellas and lively ripples in rainy days.

A raindrop fall on surface of water, creating ripples.

Ripples, stretching concentric circles

The sea of umbrellas

Raindrops create ripples, composing groups of large and small concentric circles stretching out. Under illumination of city, lively ripples bring vivid concetric light below them.

Looking down from a certain height in cities, various umbrellas emerges in crowded streets. People under umbrellas are busy walking or waiting for a traffic light, forming a elegant scene: sea of umbrella.

Light and shadow of ripples in a day of rain.

Light and shadows of ripples Raindrops fall into puddles creating vivid ripples in rainy days. Under illu-mination of street lights, lively light and shadow appears here, there and everywhere on the ground.

Sea of umbrellas on a crowded street, with every person walking and the umbrella moving, the shape of sea varied continuously.



Light and Ripples

Due to the refraction of water, the light below ripples is with bright and dark intervals.

The site is an entrance of a teaching building, which located in the corner of a campus of National Taiwan University of Science and Technology. It is a dark, windy and large semi-outdoor square.

UmbrelLight, varies when wind blows

There is always strong wind blowing at the site .

Installation of UmbrelLight

UmbrelLight Seeing that umbrella is a waterproof object that is used in everyday life, I reverse the umbrella and turn it into a water container. Making use of frequent strong wind of the site and the water inside the umbrella, ripples emerge. Add a light bulb above the water. As the light passing through the water and ripples, due to the refraction, a charming, vivid light is created, so called "umbrelLight".

Photos: Variations of UmbrelLight Because of the umbrella's shape, the shape of UmbrelLight is an octagon. This octagon varies its size and shape from time to time.

Overlay variations of UmbrelLight's outline at different moment

Variations of UmbrelLight

UmbrelLight experience

The wind blows frequently at the site, so the ripples emerge and change from time to time. "UmbrelLight", refracted by the water varied as well. The continued change is the fascinating and charming part of it.

People below the umbrella experience the variation of UmbrelLight. Walking close to the umbrella and looking up, they would be fascinated by this lively light.


Construction After the structure design and our fabrication, UmbrelLight was realized.

b. Use square hollow steel pipe to form grid frame system, fixed which on L steels Transparent Umbrella

a. Use L steel to ring the column

c. Fix small U steel on grid frame system. Umbrellas are bounded on small U steel.

d. Structure system of one section within four columns

The whole structure system Grid frame system Regarding to the location of columns, which bear the weight of whole installation, I applied the grid system since it is an easy-to-construct system that could distribute weight evenly and effectively.

The structure system was separated into three parts. L steel part transfers weight of installation to columns, the structure of the building. Square hollow steel pipe form the grid frame system, make it possible to allocate the umbrella at the desired position. Small U steel is used for fixing umbrellas to the frame system and controlling the height of umbrellas.

The distribution of Umbrellas Umbrellas was allocated according to the designed experience for people who walking through this square. Locations of columns are also taken into concern since they are the structure bearing all the weight including frame system and umbrellas.
