Its creator calls this machine the Lego Great Ball Contraption. Built in his house by Lego genius Akiyuki over the course of two years, for a total of 600 hours of construction time, the machine has staggering dimensions: 17 modules that process 500 balls for a length of 101.7 feet (31 meters) at a rate of one ball per second. The total size is 5 by 21 feet (1.5 meters by 6.5 meters).
