GBCs are cool because they’re built separately by many different users, then brought to a convention with the expectation that they’ll work together. I love the dizzying variety of ball-moving gadgets! This one was built by 7 Danish, Belgian, and Dutch builders with a world-record 93 mechanisms linked together. The contraption was featured at Lego World 2011 in Copenhagen.

Gahh!!! Stop pitching more balls in during the whole run when someone is taking a video. If you want to be the worlds longest/best/whatever make it work better. Or at least add balls off camera.
There is no payoff at the end! I got really excited, watching for 12 minutes waiting for this giant contraption to turn on a light switch, or feed goldfish. I was so bummed out to see that it was all just a loop!
Plus, at points I had a hard time following the camera work.
Either way, those are minor points in an otherwise fascinating system of Rube Goldberg twists and turns.
