Der Flügelflügel spaceship
This project is for developing an open source design of a spaceship with the form of a grand piano.
Its german name means "Grand piano wing".
Its purpose is to provide a concert hall, with a beautiful sight to the stars.
This sight would be achievable whenever the tripulation opens the grand piano lid.
Their tripulants may also have the mission of playing humankind's music across the most remote confines of the universe.
