  Using your analogizer - consider cause/effect.
  With the right balanced mechanism, a slight disturbance can be
  all it takes to get something started that continues on its own
  beyond that.

  The effect feeds back into the cause, allowing for further
  causes. [I'm not doing a "proof of God" thing here... but this
  *is* a damned amazing mechanism. I was looking for an
  engineering equivalent to mechanism with minimal cause that has
  long-lasting effects and, surprise of surprises, up comes a
  novel watch mechanism.]
  You don't even need sound on to watch this. I'm watching it
  without sound. It's beautiful to watch this ... watch.
