A point marks a position in space.
In pure geometric terms, a point is a pair of x, y coordinates.
It has no mass at all. Graphically, however, a point takes form as a dot, a visible mark.
A point can be an insignificant fleck of matter or a concentrated locus of power.
It can penetrate like a bullet, pierce like a nail, or pucker like a kiss.
A mass of points becomes texture, shape, or plane.
Tiny points of varying size create shades of gray.
