Is there a natural universal analogue of Brownian motion for random surfaces or membranes? If so, are there essential differences between these random real-valued functions defined on an interval (i.e. Brownian motion) or on a piece of the plane (this random membrane)? Are they really random surfaces? Is there a way to describe their topography? We will try to discuss and partially answer such questions.
