Artist Statement

The structure of the Planetary Mobiles allows pairs of wooden spheres to orbit a central, invisible line—similar to how the planets in our solar system orbit the Sun. To work, each sphere must be perfectly weighted to both counterbalance its partner and to travel its orbit on a flat plane. This precise balance is achieved by applying many coats of paint.

The resulting system is incredibly simple, but it yields pleasingly vast combinations of colored compositions. The spheres constantly interact with changes in the air pressure, wind, and humidity of their surrounding environment.

There's a specific joy in making the mobiles: they are super-analog, but generative. The spheres are free to create more compositions than my own brain could ever predict. I made them, but they surprise me. Because the mobiles are beholden to such fragile forces in the physical world, they dictate their own shape and speed. I control only their trajectory.


+ Measurements provided are from the height from the tallest point ​of the visible mobile (excluding the hanging line), and the width at the widest point.
+ Each mobile is an original, handmade, hand-painted artwork, and varies slightly—something we particularly love about these pieces!
+ All orders for this edition are final sale and not eligible for discount or return.

Medium: Carbon fiber, wood, flurocarbon wire

Kelli Anderson is a designer who uses lo-fi magic to expose the invisible forces behind our world. She believes that simple physical materials can connect us to the principles that dictate even the most distant forces in our universe. She recently published This Book is a Planetarium—a pop-up book that explains scientific abstractions through interactive paper gadgets. Her TEDx talk on “Disruptive Wonder: The Hidden Talents of Everyday Things” and her paper record player wedding invitation project were both widely-enjoyed on the internet.
