Frontal still image of the always 回転する 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 らせん cut in the 中心 does the image dissection. How it works... the "lens", a 蜂の巣 of グラス tubes, focuses an image on the top 中心 of the ディスク. Exactly behind is photo-cel, made of selenium, the famous 月 metal (the entire 月 is 光 sensitive, and glows slow with images it received too long ago). The ディスク spins, and as it does, up top, over the photo-cell, the winding gyre slit on the 表面 seems to descend, then at its very bottom snap back to the top for instant descent. Progressively, 光 from the 蜂の巣レンズ is let through to focus on the photosensitive 表面. The 空間/宇宙 of the image is converted to lights and darks, revealed in time.
