Method for providing a liquid display displaying a pattern (20-29, 45-48, 58-62) • by selecting a pattern (20-29, 45-48, 58-62), • by generating an adjustable liquid stream defined by a boundary along its path, and • by emitting light rays , in the form of two or more sequential light pulses with different light parameters by a first emitter, and light deflecting means (17-19, 39-43, 60-62, 82), such as gas bubbles or particles in the form of packets, by a second emitter, into said liquid stream along its path and depending on the selected pattern (20-29, 45-48, 58-62) such that each light ray within the liquid stream is guided by total reflection at the boundary of said liquid stream until impacting said light deflecting means (17-19, 39-43, 60-62, 82) by which the light ray is deflected in order to leave the liquid stream as deflected light rays , and that the deflected light rays form the selected pattern (20-29, 45-48, 58-62) to be observed by an onlooker, characterized in that the colors, intensity, emission frequency and time length of the light rays , as well as the emission and the kind of the deflecting means (17-19, 39-43, 60-62, 82) are determined and the emission frequency of the emitted light deflecting means (17-19, 39-43, 60-62, 82) is tuned to the emission frequency of the emitted pulses of light rays , or, vice versa, the emission frequency of the emitted pulses of light rays is tuned to the emission frequency of the emitted light deflecting means (17-19, 39-43, 60-62, 82), such that cinematographic light effects are created by displaying the pattern as a stationary pattern or as a pattern moving upstream inside the liquid stream. • by selecting a pattern (20-29, 45-48, 58-62), • by generating an adjustable liquid stream defined by a boundary along its path, and • by emitting light rays , in the form of two or more sequential light pulses with different light parameters by a first emitter, and light deflecting means (17-19, 39-43, 60-62, 82), such as gas bubbles or particles in the form of packets, by a second emitter, into said liquid stream along its path and depending on the selected pattern (20-29, 45-48, 58-62) such that each light ray within the liquid stream is guided by total reflection at the boundary of said liquid stream until impacting said light deflecting means (17-19, 39-43, 60-62, 82) by which the light ray is deflected in order to leave the liquid stream as deflected light rays , and that the deflected light rays form the selected pattern (20-29, 45-48, 58-62) to be observed by an onlooker, characterized in that the colors, intensity, emission frequency and time length of the light rays , as well as the emission and the kind of the deflecting means (17-19, 39-43, 60-62, 82) are determined and the emission frequency of the emitted light deflecting means (17-19, 39-43, 60-62, 82) is tuned to the emission frequency of the emitted pulses of light rays , or, vice versa, the emission frequency of the emitted pulses of light rays is tuned to the emission frequency of the emitted light deflecting means (17-19, 39-43, 60-62, 82), such that cinematographic light effects are created by displaying the pattern as a stationary pattern or as a pattern moving upstream inside the liquid stream. <EOS>
