Left foot tapper

So often one taps one's right foot to a jaunty rhythm. Alas, the left foot is usually forgotten and remains motionless. A "Left-Foot Tapper" utilises the motion and energy of one's right
foot to force one's left foot into a tapping motion.

NOTE: This is only available as a left foot tapper for right footed people - it has so far proved too impossible to produce a "right foot-tapper".
