A collaborative installation between Mike O’Toole, Andrew Ratcliff, Ian Charnas and Andrew Witte, the Waterfall Swing is an intelligent swing set made from mechanical water jets (solenoids) that create a falling plane of water in the path of the swinger. However, just as the rider reaches the rainfall the water parts briefly, ensuring nary a drop dampens their swinging.

The swing was unveiled at the 2011 World Maker Faire.
