It’s by German designer Ingo Maurer done in 1997. The “Zettel’z is a grand chandelier where the Bohemian crystal drops are substituted by scribbled paper notes from some incurable romantic’s desk. The light shines through the paper mobile. In this work Maurer plays with traditional approaches to chandelier manufacture, using precious and semi-precious materials.”
I like to think of it as a great plotting tool. Wouldn’t it be a fun way to plot out a story? You can arrange and rearrange the scenes while letting the light shine through to show you the way. Just be careful to not get burned!
