Nothing beats taking a converging lens and sheet of white paper and aiming
them at a window so that a visible image of the outside world (trees other
buildings, etc) is formed on the paper. If you have a diverging lens with
you find that you can not due this, despite the fact that *you* can look
through the lens out the window and see the outside world.
