Sky Snake is a dancing kinetic sculpture. A rotating, spinning chain creates harmonic wave patterns or figures familiar to Lye's other works, and traveling waves that move up and down the chain. A brass ball at the bottom end of the chain represents the head of a snake.  

The are two versions of Sky Snake - one is a single Snake, shown at the Albright Knox Gallery in 1965, and recently reconstructed for the Museum Tinguely exhibition in Basel, Len Lye - Motion Composer. This single Sky Snake is exhibited closer to the floor than the version at the Len Lye Centre, which has seven higher Snakes in accordance to Lye's instructions.
