Your eyes and brain "want" to see patterns and familiarity.

Try this: Close one eye, and hold a pencil about 10-12" away from your monitor. Focus on the pencil point, and gradually move it closer to the screen. You'll notice that the "faces" become a lot more obvious when they're slightly out-of-focus.
