This four-track rolling ball sculpture is a great example of how dramatically powder coating can change the appearance of stainless steel. The matte black finish creates a strong contrast with the white balls, making their movement through the sculpture especially easy to follow.

One track features a loop-d-loop with 10 inversions. Nine loops plus an inverted exit create the tenth inversion, using a full 12-foot length of stainless steel track.

Other kinetic elements include a free-swinging tipping arm that continues rocking back and forth after the ball passes through, and a U-shaped track at the lower right that sends the ball repeatedly from side to side. As it gradually loses momentum, it eventually reaches the bottom and rolls into the collector tray.

The four tracks also include horizontal zig-zags, another tipping arm, a flat spiral, and plenty of sweeping curves before all of the balls return to the lift and begin the cycle again.

Made from 100% stainless steel, TIG welded and finished with matte black powder coating.
