So the last piece to the puzzle is the intro of the animation where the lone screw begins its chain reaction to bring the machine to life.
I tried to bring in a handle to which would start to move after the screw screwed in place. I think in this edit it maybe a little to busy and Im not sure on the handle placement. I think it may need to be more connected to the screw by maybe having it underneath rather than to the side. However, I do like the delay before the cog begins to turn ( the one behind the screw) rather than the instant turn with the handle.
