I love pinball, personally terrible at it, I always thought a some luck came into play depending on where the ball was dropping/heading, until I watched someone actually good at pinball play.

He showed me there is a fine art in bumping the machine subtly enough to move the balls line so you can stop it from going straight down the middle or into one of the dead lanes... but not so much to trigger the sensors to shut the machine down.

Watching him play pinball blew my mind. I've never been able to do what he could do, but it's definitely an art form...

So, can you implement machine bumping? :-)
