Up and down I fall
Back and forth I sway,
And if left alone,
Round and round I go.

(In reply to Pendulum by brianjn)

Ahh, now I remember my high school physics.  When you look at a pendulum from a side view you see a motion that is up and down.  The pendulum is moving in a circle relative to the earth, and it moves side to side...
