The Lego Great Ball Contraption

by James Furbush on September 19, 2012

Jesus Diaz sums this LEGO machine up perfectly: “I’ve no words to describe the awe that I’ve experienced watching this video. It surprised me at every step. I’ve never ever seen any contraption so glorious and crazy.”

It was built by Akiyuki over the course of two years (roughly 600 hours of construction time in total) and features 17 ball modules.
