I believe you're looking for "perpetual motion" which doesn't really exist, but can sort of be simulated.
I'm really not good at writing signatures. I mean, what is it that you're really trying to do? Write something that somebody's actually going to remember, or even read? Yeah right! Nobody ever actually reads these things.
