After viewing James Cody Hovland's kinetic ship sculpture, I realized that wind-driven sailing ships are just big wind-powered buoyant sculptures, and that the same principles behind moving sailing ships are used for wind-powered artistic sculptures.
Hovland's kinetic ship sculpture explores beyond simple wind propulsion and transforms the entire hull of the model ship into a mechanical entity with a life of its own. Curiously, the hull of the ship seems to drive the movement of the sails at times.
Natural Kinetic Movement
Snakes almost seem like a kinetic sculpture themselves - they move with a rhythm not found in most animals. After doing a little research I learned that snakes propel themselves on their scales which are designed to slide the snake forward while catching on the ground as they move side-to-side. So, in terms of Visualization, the snake is made up of a hierarchy of joints that rotate on an axis while translating eachother forward. The movement is re-created in wooden toys that you see at places like Hobby Lobby. The concept of connected joints like a snake's skeleton could be an interesting way to create a kinetic sculpture.
And just for fun:
