An ingenious fixture stabilizes and decorates the dynamic stage as it collapses and expands. The machine has no floor, but extension brackets, and into these are fixtures, set into a grooved track. The fixtures are spheres, grooved around circumference, into which a telescoping arm is set. Both the sphere and arms can twist, and the arm can also bend. The other side of the arm is a hook to connect to stations of the stage.
When the background collapses in front of the fountains, the gridded gate closes in front of them, and fixtures secure it shut.
