CTBC BANK – Multimedia Interactive Installation Art

To present the brand intentions of CTBC by creating a permanent massive interactive design in the Lobby A of its new headquarters in Nankang.


By using the endemic species of Taiwan as the main content, an infinite circulation was designed to express and appreciate the values of their homeland, Formosa Taiwan.
To emphasize the brand symbol of CTBC, the structure was inspired by the “Double-C Logo,” which was designed by, Jeffrey Koo, Sr., founder of Chinatrust. The double C represents their endless affection for Taiwan and their corporate mission to “protect and create.”


Environment / Time:

DEM received the task when the construction of Lobby A was almost completed. As a result, the structure and load bearing needed to be recalculated to install this ten ton device. With only three months of construction time and without any changes to the original design as a top priority, to build such a massive device required rapid and intense communication with the vendors on every detail.


When the sketch of the Double-C logo and the artistic styles were settled, the DEM team realized that building a huge art piece wouldn’t stand out from the other interactive installations. Therefore, the team decided to take the challenge to a whole new level of complicity and difficulty by incorporating big data streaming and real-time rendering.
This challenge caused many technical issues within a limited amount of time. Yet in the end, it turned out to be not only a magnificent artwork, but also a vital, breathing, and, interactive digital art piece.

Big Data:

Starting from the concept of real-time data, choosing the data to be streamed required over twenty meetings with CTBC, since adding the real-time data was absolutely the most challenging part. Combining the global population, corporate data, and climate information on a digital installation was certainly the first-of-its-kind in Taiwan.


At the initial stage of this project, due to the overwhelming scale and limited time for execution, the entire company was involved in the planning through countless weekends. The brainstormed ideas were too decentralized to focus on and were tossed back and forth, which caused the whole team to be stuck in a constant state of dilemma. Just when everyone was nearly burned-out, the team started to focus their logic onto the logo of CTBC by discussing the different meanings behind it, which were then infused into the piece through the language of art and design. At last, the concept for the world class digital installation art piece was complete.


This installation required a team of over 100 experts from various fields of fine arts, engineering, architecture, design, and programming, which took about six months of planning and execution.
The sound effects were equivalent to the level of hardware used in the Louvre, with fourteen sets of directional loudspeakers, two sets of surround sound speakers, and fifteen amplifiers to build the soundstage. The sounds of the native Taiwanese birds were recorded live as well.
Sixteen computers and seven sets of soundcards were also used as the core processor, along with eight position sensors to create seven real-time rendering zones.
The huge 3D LED matrix near the ceiling was built with 120,000 LED circuits.
On the back of the LED wall, 21 frameless HD monitors were combined as the introduction wall. The total resolution was up to 8K (2304×8192), which is more than double for an IMAX theater.
To connect the backstage data, nine kilometers of wires were used in the construction, while more than 2,400,000 LEDs and 3,000 LED panels were adopted to complete the sixteen individual LED surfaces.


The display was inspired by the Double-C logo, which was designed by, Jeffrey Koo, Sr., the founder of CTBC.
The installation art was divided into five main components. The waterfall and the pine tree, which is in memory of the late founder, are connected to a pool that represents the origins of life that provides for the thriving grasslands and the blooming flowers. The birds and the extending tree branches would bring hope to the clouds, which would then carry this dream back to the waterfall.

The 17 meters high by 17 meters wide piece is not only an extremely large LED sculpture, but also an interactive digital art piece. The 360 degree annular piece is named, “Circulum Formosa”, to illustrate the value of an everlasting cycle of life.
“Circulum Formosa” is programmed to instantly calculate and simulate the random variations of nature by precisely expressing every line, color, pattern and structure. The natural elements on the display start from the clouds on the sky, to the water that flows from the waterfall and ending in a river pond. Around the pound, flowers would blossom and scatter into the air, while the birds would gather around the plants and the tree before bursting into a sky filled with flowing clouds. Every phenomenon is continuous and constantly cycling without the same scene never repeating.

Through real-time rendering, the images are displayed instantly, with the constant change of shapes and patterns by calibrating the audience’s movements, the time, seasons, climate and the environment around the CTBC Financial Park. This digital installation is an art piece that pulses with life, like a scene in nature that never repeats itself. The device will keep creating a new status infinitely and change its appearance according to the four seasonal changes. Furthermore, a total of 55 endemic or featured species in Taiwan are presented in the piece. Details of the species can be found on the website, which adds another value of education to the art work.
