Created by Lego Mastermind Akayuki, the Akayuki Ball Contraption is an absolute wonder to behold.
The first thing to note about this crazy contraption is its immense size. At 21 feet long and five feet wide, the project took Akiyuki 600 hours to complete over the course of two years. But far more impressive than its sheer size is the amount of technical genius exhibited in the 17 modules it's composed of.
There are zig zag staircases, pneumatic lifts, basketball shooters, spiral slides, conveyor belts, robotic transports and even a mechanical train that carries loads of balls between different sections.
Anyone who has ever given up on a construction project because of its high degree of difficulty should definitely check out the Akayuki Ball Contraption. Just one look at this toy brick behemoth and you'll be inspired to build again.
