Patent ID: 8807452

Claim:
An apparatus for producing reconfigurable walls of falling water droplets, the apparatus comprising: an array of spray bars, each spray bar of the array of spray bars capable of producing a wall of falling water droplets over a distance, the array of spray bars located so that each spray bar can be used to produce a wall of falling water droplets; an array of water valves, each water valve in the array of water valves associated with only one spray bar in the array of spray bars, each water valve in the array of water valves capable of being placed in a first state in which water is allowed to flow to the spray bar with which the valve is associated and a second state in which water is prevented from flowing to the spray bar with which the valve is associated, the array of water valves capable of being used to: (a) provide water to a first subset of the array of spray bars so that the first subset of spray bars produces walls of falling water droplets that contribute to defining a first maze and (b) provide water to a second subset of the array of spray bars so that the second subset of spray bars produces walls of falling water droplets that contribute to defining a second maze and that is different than the first maze; each spray bar in the array of spray bars extends from a first terminal end to a second terminal end, wherein each of the first and second terminal ends presents two planar surfaces with an angle between the two planar surfaces being other than 180 degrees, wherein each of the two planar surfaces is adapted to facilitate miter-style positioning between adjacent spray bars that are not collinearly disposed.
