/* Emits a 7-Hz tone for 10 seconds.
  True story: 7 Hz is the resonant frequency of a
  chicken's skull cavity. This was determined
  empirically in Australia, where a new factory
  generating 7-Hz tones was located too close to a
  chicken ranch: When the factory started up, all the
  chickens died.
  Your PC may not be able to emit a 7-Hz tone. */
