  We report the incorporation of the Wiimote, a light-tracking remote control
device, into two undergraduate-level experiments. We provide an overview of the
Wiimote's basic functions and a systematic analysis of its motion tracking
capabilities. We describe the Wiimote's use in measuring conservation of linear
and angular momentum on an air table, and measuring the gravitational constant
with the classic Cavendish torsion pendulum. Our results show that Wiimote is a
simple and affordable way to streamline the data acquisition process and
produce results that are generally superior to those obtained with conventional
techniques.
