Every LEGO bricks begins its life being cast in plastic from a mold. For builder Olle Moquist’s last creation, bricks become molds for a new building material: concrete. Inspired by the concrete sculptures of David Umemoto, Olle started with a traditional LEGO build, used it to create a silicone mold, then poured concrete to create this incredible creation. A single red minifigure and dark blue microfigure offer a pop of color and clarify scale.

Up close, the subtle imperfecti0ns in the pour add an air of weathered beauty. Even though the cast is just days old, it looks timeless – a relic from an alternate brutalist timeline where grey-clad children play with concrete blocks.
