When I was a kid we built simple things out of legos. Even the Frank Lloyd Wright designs seem difficult by comparison to the old days of lego building. The crazy difficult designs were normally just boats and planes. Apparently people nowadays build things you can actually use, like this Lego Printer. There aren’t a ton of details as to why he did it, but the builder did post a FAQ below the video on YouTube. It’s pretty impressive if you ask me.
