Here’s a cool video showing an impressive LEGO Rube Goldberg machine. While I’m not exactly sure what the end result is, it’s flipping down some Japanese? letters/numbers? that spell out something I guess- the mechanics of it are pretty impressive. That and the fact that it’s labeled as “take 187” because personally 150 takes is my limit before I take the sledgehammer to my LEGO construction. But that’s just me.
