One sunny day, I stepped into an outhouse.  When the door slammed shut

behind me, it was so dark that I could not see anything.  As my eyes began to

adjust, I noticed some colors flickering on the wall.  When I leaned forward to

investigate, the colors disappeared.  As I leaned back, they reappeared. 

Turning to the opposite wall, I blinked as a beam of light hit my eye.

      A hole in the wall was letting in a small amount of light, and this was

creating blue, brown and green colors on the opposite wall.  I moved closer to

the colors—while not obstructing the beam—and saw an upside down image of the

forest and sky outside.  The trees were even swaying in the breeze. 

Coincidentally, I had a moment to think about this phenomenon.

      A dark chamber that is penetrated by a small amount of light will cause an

image of the outside to be created on the inside.  It was as if I had stepped

into a camera.  A camera is a dark box that light enters when the button is

pressed.  If I had had a big roll of film with me, I could have made a picture

of the trees for my photo album.

      Also, it was as if I had stepped into an eye.  Your eye is a dark chamber

that can be penetrated by a small amount of light when you raise your eyelid. 

The image that is created in your eye travels to your brain, which gives you

your sight and a memory of what you have seen.
