Long ago, I became deeply interested in Indian classical music and bought myself a beautiful instrument — the sitar. Its resonating chamber has a lovely organic shape, and I learned that it is made by growing a gourd inside a pit carved into the desired form.
Over time, I encountered more and more advanced ideas about using organic growth in practical ways, until I came across the claim that some extraterrestrial civilizations build their spacecraft through organic growth. In a sense, this kind of ship is a living organism, and it can be controlled telepathically — so there is no need for any buttons or levers.
