THREE DIMENSIONAL DISPLAY DEVICE USING WATER FOUNTAIN

摘要

A three dimensional water fountain display device has a nozzle matrix in which the nozzles are arranged in a series of vertical steps and in aligned relation. The nozzles are thus able upon the discharge of water from selected nozzles to display desired characters, numerals and other notational representations. An electromagnetic valve is operatively connected to each nozzle, and a controller circuit is associated with each valve so as to enable the display of the desired pattern of characters, numerals and other notational representations in three dimensions by a combination of selected nozzles in operation.
