Frontal still image of the always rotating Nipkow Disk, central and metal-made component of an Image Dissecting system proposed in the 1880's by a Berlin student who, in later years, was proclaimed by Adolf Hitler to be the Father of Television. The spiral cut in the center does the image dissection. How it works... the "lens", a honeycomb of glass tubes, focuses an image on the top center of the disk. Exactly behind is photo-cel, made of selenium, the famous moon metal (the entire moon is light sensitive, and glows slow with images it received too long ago). The disk spins, and as it does, up top, over the photo-cell, the winding gyre slit on the surface seems to descend, then at its very bottom snap back to the top for instant descent. Progressively, light from the honeycomb lens is let through to focus on the photosensitive surface. The space of the image is converted to lights and darks, revealed in time.
