This is Clockwork, my fifth major K'nex ball machine, and my largest and most complex K'nex structure to date. It took 8 months to build, has over 40,000 pieces, over 450 feet of track, 21 different paths, 8 motors, 5 lifts, and a one-of-a-kind computer-controlled crane, as well as two computer-controlled illuminated K'nex balls.As requested, here is a raw video of the machine with the original sound:, a video of the machine running at night with the LED balls: people have been asking about the music, it is an original composition I wrote specifically for this machine and this video. You can find it here: 3D panorama of the machine: exposure of the machine running at night: more videos of specific details of the machine, as well as construction history, visit my channel!If you have any questions, send me a private message or email me at
