This is a video of the Great Ball Contraption (GBC) of Japan Brickfest 2025, constructed using 49 different ball-moving LEGO modules from eight master LEGO builders. The machine spans a very respectable 31 meters (102 feet). Damn, that is a lot of ball moving! Me? When I’m uncomfortable at the dinner table and need to move my own I do it like a gentleman: awkwardly squirming in my chair until somebody asks if I pooped myself and I regret not just using a salad fork.
