If you told someone you were about to spin this cam round 230 times a second, and the follower would remain in contact with the cam surface via the mechanical wizzardry of "a big spring" you'd think they were mental.
I'm always very pleased that the inner workings of cars, planes* etc are just that - inner. I would hate to see it all cut away and have some idea of all the things that could go wrong.
