Animation showing how Maltese cross in gear mechanism works.

The Geneva drive or Maltese cross is a gear mechanism that translates a continuous rotation into an intermittent rotary motion.

The very purpose of our life is happiness, which is sustained by hope. We have no guarantee about the future, but we exist in the hope of something better.
