And the cameras of mobile telephones are sharp, and if the tale objectives are putting on those cameras, that would be a very powerful tool. One of the most fascinating ideas is to use a camera obscure with those cameras and drive the light through the small hole, which allows projecting the images to the wall of the box. Then the images can be taken from the wall by using the periscope, and that thing would allow looking at them by using magnifier or microscope.
