title: Algorithm for "smooth" random numbers
body: <p>Could anyone give me a hint on how to generate "smooth" random numbers?
  Here's what I mean by smooth:</p>
  
  <p>The random numbers shall be used in a game, e.g. for wind direction and strength (does anyone remember goood old "Worms"?). Of course setting random numbers for those values every second or so would look awfully choppy.
  I would rather have some kind of smooth oscillation in a given value range. Sort of like a sine wave but much more random.</p>
  
  <p>Does anyone get what I'm after? ;-)
  Any ideas on how to achieve this kind of behavior would be appreciated.</p>
