LIKES

Great Ball Contraption Rainbow Wave designed by me. It has 38 Lego colors and about 1150 moving parts. It is powered by a single motor, with each of the colored pistons sitting on an 8-tooth gear. Each piston’s gear is exactly 1 tooth offset from its neighbors making one wave 8 colors. The GBC is level so the balls are moved by the waving surface. The initial digital model and building instruction was created by Laurent Fournier (Courbet).

Current building instruction is version 2 with 4 extra power repeaters to prevent too much friction.
