The idea of the Great Ball Contraption is to take modules from many builders and combine them into one large machine. The modules need to find some way of moving LEGO*soccer balls*and basketballs from an input point to an exit are that passes them onto the next module. Some of them sort the balls, but in the end the eight-and-a-half-minute video above shows the orbs going around and around. That’s just fine with us, it’s no secret that we love machines that are overly complicated and may be completely useless.
