while your comment is probably not appropriately worded for this community here, I have to agree: The pigs jumping around in the machine gave the video a new surreal dimension.

Consider all the work that went into this creation.

Finally - after everything is finished and everything works, the author takes his time to show us around. He's showing all the little details. All the ingenuity in the various components.

And then, in the middle of the tour, you see pigs jumping around.

I don't know. Maybe I have a simple mind, but I was highly amused - especially knowing what a piece of art the creator of the video was showing us.
