David Morrell hat mit „Sphere“ eine Murmelbahnkugel gebaut, die in einen Raum gehangen wird und auf 270 Meter Draht Murmeln in sich transportiert.
„The sculpture has ten different track paths with loops (both small and large), four tipping arms, balls on track, Ferris wheel ball lifter, serpentine, zig-zag, semi automated switch, two ball switch, ball collector jump, ball collector, spinning arm, three tall spirals, oval flat spiral, conical spiral and plenty of track! the helical lift has three guide tracks, delivering the marbles back to the top of the sculpture. Each set of marbles remains independent of the other two sets.“
