This illustration was to demonstrate a metaphor using human anatomical parts. I chose to render the mitochondrion, the nervous system and the spine. The mitochondria in the body produce the body's ATP or "energy." This powers our various bodily funtions, including our nervous system. Our nervous system then mobilizes our spine. The panels also feature similar information through the background, showing the realtionship between a power plant, electrical grid, and a city. The same relationship exists here, in that a power plant creates the energy for an electrical board, which makes the city operative and mobile.
