From Pathfinder Wiki
The Great Ball Contraption (GBC) is a popular collaborative LEGO building theme. A GBC is essentially a Rube Goldberg-style machine made from LEGO (primarily Technic elements) that continuously moves small LEGO balls (soccer/basketball style) from one module to the next in a chain, like a bucket brigade. Modules connect seamlessly when built to official GBC standards, allowing large group displays at events and shows.
