“Marbles” was made by light designer Daan Roosegaarde. It consists of large-sized works that give visitors an interactive experience through the mediums of sound, light and color. Inside the mountain-shaped works are installed LED lights and smart sensors. When someone touches them they change colors to express emotions from “Boring” to “Fun!” The “marbles” can sense each other, enabling them to amplify their responses. “Marbles” transform everyday settings into playgrounds where light and people interact.
