Akiyuky's Lego Great Ball Contraption Collective
We've featured GBC's (Great Ball Contraptions) and other contraptions multiple times before by Youtube user/Lego fanatic Akiyuky, but this is the first time we've seen a collective version featuring some of the best Lego tinkerers in the area. The goal of a GBC is to simply ferry a ball from one place to the next, while showing off your prowess with advanced Lego engineering. The end result is always an infinite loop, but it's always entrancing to see how each creator approached the same problem.
