Explore the lifts, track switches, spirals, loops, zig-zags and other kinetic elements I design and build for my rolling ball sculptures.

A rolling ball sculpture is a kinetic art sculpture that uses gravity, motion, and mechanical design to guide balls along intricate tracks. Learn how rolling ball sculptures work, their history, and why they captivate audiences worldwide.

I rarely design a rolling ball sculpture completely on paper. Here's how I build the frame, lift, tracks and elements while controlling ball speed, movement and reliability throughout the process.

Rolling ball sculptures put STEM concepts into motion, making gravity, momentum, friction, energy transfer and engineering visible. See how kinetic art and hands-on experimentation can create engaging exhibits for science centers, children's museums and educational spaces.

Explore the physics behind rolling ball sculptures and how gravity, momentum, friction, kinetic and potential energy, and centripetal force shape the movement of every ball.

Rube Goldberg machines and rolling ball sculptures share gravity, motion and mechanical ingenuity, but they are built for different purposes. Here’s where they overlap - and where they differ.

George Rhoads was my biggest influence when I began building rolling ball sculptures. His large, playful ball machines inspired my early work, and I still admire his creative approach to kinetic art more than two decades later.

A collection of rolling ball sculpture resources, artists, builders, suppliers and useful links for anyone interested in kinetic sculpture, marble machines and rolling ball art.

How I make adjustable pivot points for rolling ball sculptures using a custom drilling jig, allowing switches and moving track elements to be precisely positioned and adjusted.

How track switches divide and redirect balls onto different paths in a rolling ball sculpture, creating changing routes, movement and visual variety.
