Incredibly Elaborate LEGO Great Ball Contraption
The LEGO Great Ball Contraption is a mesmerizing and incredibly elaborate room-sized ball machine made out of LEGO components. Akiyuki, the machine’s Japanese creator, spent two years building the 17 modules that the plastic balls pass through in a continuous loop. It’s worth watching the entire 7 minute video to see every module in action.
