Featuring numerous great ball contraption mechanisms in a closed circuit, the GBC showcase creates a fascinating display piece that celebrates LEGO engineering.
Each module highlights a unique GBC mechanism carefully selected to bring a scene to life. Watch as the balls wash along the sea floor, spiral up a power reactor, drift over the ocean waves, ascend an old windmill, paddle up a winding stream and scale the tower steps.
I hope you enjoy watching the GBC showcase in action. If you like the idea, please show your support by voting!
