Looking at the Heart from Different Angles
To illustrate this point, consider this:
 - There are 12 windows to look through to see the heart.
 - Depending on which window you look through, you will
see a different view.
 - The Electrodes are the stickies or the eyes. “The sticky sees”
 - Suppose you are buying a house and wanted to show your
friends what it looked like.
 - A picture would give them some idea of the size and shape of the
house.
