Embodiments herein describe a dripping system that displays an animation using different colored light sources. In one embodiment, the dripping system includes red, green, and blue light sources which can be activated individually or in combination to emit light that reflects off liquid droplets emitted by the dripping system. Controlling the timing of the light sources permits the dripping system to illuminate the water droplets at different locations along their path which generate the animations. In one embodiment, the dripping system changes animations or alters the animation in response to user interaction. For example, different user hand gestures may be mapped to different water droplet animations. An input/output (I/O) system detects the user interaction and changes the displayed animation.

A method may include supplying electric power to a first light source and a second light source of at least two light sources by at least one ballast so that the first light source and the second light source emit a first source light and a second source light with a first and second spectral light distribution, respectively. The method further includes superimposing the first and second source light using an optical unit such that the lighting device outputs light with a spectral superposition light distribution. The method further includes detecting the light outputted from the lighting device using a light distribution sensor that provides a sensor signal corresponding to a spectral light distribution of the detected light. The method further includes comparing the sensor signal to a predefined spectral light distribution and adjusting the electric power supplied to the respective light source by the ballast based on the comparison.

A color changing display system includes a fabric body, a light source connected to the fabric body, a controller electrically connected to the light source, and a combined printed image comprising two or more images printed in a single layer on the fabric body. The light source is for producing different light colors. The controller is configured to control the light source to provide a smooth transition between the different light colors. The images are different colors. Each of the different color images reacts with a respective color of the different light colors such that an appearance of the combined printed image changes gradually from a first display image having one particular shape into a second display image having a second particular shape in response to the different light colors interacting with the combined printed image to produce a moving, seemingly holographic effect.
