We check out the assembly of Great Ball Contraption modules at this year's Bricks by the Bay LEGO convention, which brought together builders from around the world in this mesmerizing 46-module machine. Builder Lawrie George explains the rules of GBC and shows off his delightful mini-golf course modules!
