ThinkPads used to have accelerometers to protect the hard drives, so if you dropped the machine or treated it roughly, it could park the drive, protecting it from data loss.
People used to write Linux utilities that read these accelerometers, allowing for example to switch virtual desktops by physically smacking the machine on either side.
