Leonardo Da Vinci quote: "Who would believe that so small a space could contain the image of all the universe? O mighty process! What talent can avail to penetrate a nature such as this? What tongue will it be that can unfold so great a wonder? Verily, none! This it is that guides the human discourse to the considering of divine things. Here the figures, here the colors, here all the images of every part of the universe are contracted to a point. O what a point is so marvelous!"--Leonardo Da Vinci's comments on the "Camera Obscura" (Dark Room), or what we today call the pinhole camera.
