We present the principle of a membranous mirror, free-floating at its edge and tied at its center. Its shape is controlled from a control surface, which is itself a membrane. This surface has autonomous integrated means for measuring, analysing and acting upon the mirror. We discuss the possibility of building gound-based or space telescopes using this concept.
