Endless Ripples is a growing participatory pond. It consists of white LED strings under tiled canvases and a cup with water in the middle of a pond. When visitors come in the dark space, LEDs under the cup emit dim lights to attract them to throw their coins into the cup. If they are successful, ambient noises from speakers disappear and instead, visitors see bright ripples through the canvases. The coins will be donated to the nearest public facility. The coins that fall outside the cup will be used for growing and duplicating the project to provide more opportunities for audiences to take part in. Both outcomes will contribute to helping local areas.
