two-dimensional oscilloscope responding to the activity of the brain

check out these sweet images!! 'Leibniz has, in many ways, considerably complicated the picture space. Rather than accepting the back surface of the camera as a receiving surface, standing in, so to speak, for the painter's canvas, he has himself stretched a canvas in the space, as a receptor of the images. This screen, moreover, is not the flat picture plane of classical representation; it is from the start ridged and folded, in ways that depict already innate ideas. Locke's tabula rasa, or white sheet of paper, has no place in this box of miracles. Further, this canvas is in no way a passive instrument of the "real"; rather it moves or "oscillates" like a plucked string, according to the nature of the images coming in from outside. These movements in turn create new folds in the surface of the screen, turning it into something like a diaphragm, elastic and mobile, a two-dimensional oscilloscope responding to the activity of the brain.'
