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

What is kinetic art? Kinetic artist Matthew Gaulden explains how movement, gravity, mechanics and experimentation come together in his handmade rolling ball sculptures.

See how a rolling ball sculpture is made, from the stainless steel frame and ball lift to the tracks and moving elements, with testing and adjustments throughout the build.

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.

A $3 Spacewarp Black Wolf my brother found at a thrift store started a chain of events that eventually became my career building rolling ball sculptures.

Learn how rolling ball sculptures work using gravity, momentum and kinetic energy. See how lifts, tracks and other elements keep the marbles moving.

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.

Rolling ball sculptures have appeared in movies and television for decades. From Sesame Street and Fracture to CSI: NY and Elementary, here's a look at some memorable appearances - including a few I was personally involved in.

The rolling ball sculptures in the 2007 movie Fracture became an unexpected marketing tool for my work. A look at Mark Bischof's incredible ball machines, the sculptures used in the film, and how the movie introduced a new audience to rolling ball sculpture.

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.

Custom stainless steel pinball ramps and habitrails, fabricated from your drawings or reproduced from original ramps for custom builds and pinball machine restorations.

I design and build custom miniature golf ball lifts, ball returns and track systems using the same kinetic engineering and fabrication techniques found in my rolling ball sculptures.

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 I tap straight, accurately aligned holes for rolling ball sculpture parts using a custom guide I built to keep the tap square and consistent during fabrication.

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

How I use custom welding jigs to hold stainless steel rods at precise, repeatable angles while fabricating track and mechanical elements for rolling ball sculptures.

The adjustable lift table I use to raise and lower rolling ball sculptures to a comfortable working height during welding, assembly and fabrication.

Artist Matthew Gaulden shares his hand-drawn pencil mazes, a process that began in childhood and evolved into detailed illustrated mazes built one path at a time.
