South Facing Dragon
This is a model of a 2,000 year old military weapon. The Chinese invented the differential gear so their "dragon" always faced in the same direction no matter how the cart was twisted and turned. The military advantage was that in the heat, confusion, and dust of battle the generals could always tell what direction they wanted to advance.
