The Waterfall Swing is a creation that would delight both children and adults. It essentially creates a perpetually rainy playground. The interesting bit, however, is that it appears that the swingers don't actually have to get wet. It is an intelligent swingset that is equipped with mechanical waterjets (solenoids), which creates the waterfall effect. Yet the Waterfall Swings are controlled so that just as it looks like the rainfall will hit the swinger. Instead it parts just in time so that their playtime is not dampened.
A collaborative installation between Mike O’Toole, Andrew Ratcliff, Ian Charnas and Andrew Witte, the Waterfall Swing made its debut at the World Maker Faire. The Waterfall Swing is so impressively smart, it doesn't just part before the swinger, it can also form alphabet letters and hearts.
