The "Happy Birthday Daddy" Mechanism Running Without the Top-WorksI am often asked how everything works as people try to peer into the inner workings of a completed project. I took a minute to make a video of the mechanism elements as they relate to the motion of the characters. I hope that the curious find it helpful to figure things out.
