"Introduced with the company's most recent round of PowerBook updates,
Apple's Sudden Motion Sensor is designed to detect any strong vibration or
sudden motion -- such as the laptop being dropped from a desk -- and park
the drive heads, lessening the chances of damage to the drive. But the
motion sensor does more than just notice sudden movement: It can be used to
determine the angle the PowerBook is tilted at in any direction, along with
the velocity at which the computer is being moved.

Enterprising hackers have discovered that because the new motion sensor
returns reasonably accurate measurements to Mac OS X, it can be used to do
some cool tricks, from realigning an image in a window so it always points
up, no matter what angle you hold the laptop at, to controlling what's
playing in iTunes -- rock the machine backward to go to the next track,
forward to play the previous one..."
