Patent ID: 8556190

Claim:
An apparatus for pixelating falling water droplets to create a graphical image comprising a water management system for providing, controlling and maintaining a closed-loop pressurized water supply, one or more elevated water display heads having a plurality of spaced apart nozzles arranged on a replaceable nozzle plate in a manner to provide the intended display, each of said nozzles having a water inlet and a water outlet, and a high speed solenoid for each nozzle and a control means for controlling the water supply and for controlling the formation of the falling water droplets through each solenoid and nozzle, wherein a water reservoir is provided above the solenoids and the water inlets for said nozzles so that water pressure to the nozzles is maintained by gravity, and the solenoids are connected to the water outlets of said nozzles to control the speed at which water exits the nozzles and whereby water droplets falling from said plurality of nozzles form a graphical image that retains its shape as it falls and wherein a vacuum line is connected to the water reservoir to prevent water leaking through the solenoids and nozzles when the water reservoir is placed under negative pressure.
