A rolling ball sculpture is comprised of modular track parts, connected together to form a contiguous pathway for balls. Magnetic wall mount parts are assembled to a wall in an array with even spacing in order to hold magnetic support pieces that may be moved into various locations. Track pieces may be held by support pieces that mount onto the moveable supports that are magnetically mounted to permanent magnetic pieces. Track parts include straight parts, turns, and mechanisms such as chimes, switches for diverting balls along differing paths, funnels, and conveyor parts that lift balls to the top of the sculpture. Parts may be constructed of 2-dimensional parts that may be cut or stamped from flat materials, such as laser-cut plywood.
