I can easily create mental images in my mind, like a rotating wireframe cube. I can see these images in my minds eye with my eyes open. I experience these mental images as a separate sensory channel from the eigenbrau, which is much more difficult to perceive and control. To use your metaphor, my mental images are in an offscreen buffer. My eigenbrau is more like my on-screen buffer, but I can't see eigenbrau with my eyes open, presumably because then my eyes are using that channel.
