Big LEGO builds are always interesting, but usually they just sit there, being something without moving. However, LEGO master Lunatic Sekai decoded to plough 90,000 bricks into something that actually works as it should; a huge 'wooden' roller coaster.
Designed to look like the wooden El Torro coaster at Six Flags Great Adventure Theme Park, the build features working winches, a full rolling coaster, and even other rides. As you can see in the images and videos, the vast majority of those 90,000 parts are brown, making up the structure of the roller coaster.
