Great Ball Contraptions (GBCs) are one of the most fascinating and mesmerizing pieces of LEGO art out there. GBC layouts at any convention will always enjoy an onslaught of wonderstruck fans. But what those fans may not know is that many LEGO GBC modules were inspired by one person. Of course, not all of them – there’s tons of originality in the hobby. That said, a household name amongst GBC enthusiasts is Akiyuki. His incredible designs have been the inspiration for hundreds of builds. Now he’s back with an incredible new creation, his “Five Tilted Rings” module.
