A point is the most basic of the graphics. Simple, like the folktale stories mentioned before that lack description and detail. One point can be insignificant, the focus of the page, or part of something bigger, disappearing into the mass of many.
In the case of Like Stars on a Clear Night Sky, each individual star is its own point, all varying in size. Some are insignificant; others can interact with the reader by revealing a story. The speed with which one gets through the piece depends on how fast each interactive point can be identified.
