Great Ball Contraption
MADNESS! 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. Built in his house by Lego genius Akiyuki over the course of two years, for a total of 600 hours of construction time, the machine has staggering dimensions: 17 modules that process 500 balls for a length of 31 meters at a rate of one ball per second. The total size is 1.5 meters by 6.5 meters.

Mesmerizing, but otherwise useless?! It must be said that to create a machine like this you need a lot of balls.
