Abstract
Systems and methods are provided for generating light displays using fluids, such as water. An example system can include a plurality of nozzles, a light projector, a shutter, and a control system. Each nozzle can emit a sequence of drops of a fluid that travel along a corresponding path. The light projector can generate light beam(s) that illuminate a display area of the sequences of drops. The shutter can operate at a shutter frequency determined to cause the light beam(s) to intermittently illuminate a position of a corresponding path of a sequence of drops within the display area such that the sequence of drops appears to be a fixed, illuminated drop at the position. The control system can: generate timing information for emission of sequence(s) of drops, determine the shutter frequency based on the timing information, and operate the shutter at the shutter frequency.
