A Collaborative LEGO Great Ball Contraption

The Tsukuba LEGO Circle has created a crazy Great Ball Contraption (GBC) that transports balls from one place to another in creative ways. Sections of the 2013 GBC were created by Fin, Makoto Uda, Toise, Matk, Momonga, Kosaku-jin, Katsumata, Yattaran, and Akiyuki.

LEGO also interviewed Kawaguchi Akiyuki about his passion for GBC building in season four of its Blocumentary series:
