O R G / 1, 2, Lissajous

Easily mistaken for the infinity sign, the Lissajous Figure is a horizontal figure-eight named after French physicist and mathematician Jules Antoine Lissajous (1822-1880). The shape is drawn by plotting a two-variable parametric equation as it calculates and recalculates itself over time. The resulting figure is the picture of two systems falling into and out of phase.
