The project task was to design a home appliances product that incorporates a unusual material or process, that we would choose from our observations in Taiwanese culture. During my travels on the island, I dis-covered several interesting natural materials. While analyzing the structures and patterns of the Corals, I tried to apply the shape to a function of a specific product. My interest for the Patterns made me try to reproduce these structures. I tried to use different fluid materials to make a mold. While I was shaping the limestone I realized that it is very hard to manipulate. So I tried to take away the material from the backside to isolate the interesting pattern and use it as a membrane for a speaker. I decided to design a set of speakers, whose shapes would derrive from the original shape of the coral I had found. To create unique and individual shapes, but still develope a technological look, a combination of materials was required. The concept of Symbiosis also enhanced my idea. A symbiosis of natural and industrial materials that symbolizes the relation of man and nature. Most fascinating about coral stone is its beautiful and diverse structure. The pattern varies from one to the next, depending on which type of coral organism built the limestone structure. The patterns are very delicate but the structure itself is very strong and durable. The limestone is not only very resistant but has a great natural white colour. The single units of the pattern are very similar but never totally the same. Through the forces of nature the coral stones are shaped very organic and smooth. The structure of the material creates a very special haptic experience.
