The two dimensional representation of sine waves with different frequency and phase is known as a Lissajous Pattern. The figure-eight pattern described above is a relatively simple case.

Most moving lights don't move fast enough to let you see the full beauty of some of the more complex Lissajous patterns, but the effects engine does let you play with basic versions. I like to think of it as the adult version of a spirograph.
