It’s no secret that most LEGO is made from dinosaurs and carboniferous forests. But you have to drill hundreds or even thousands of meters beneath the surface of the earth to pump out that crude pre-LEGO material, often from platforms way out at sea. General Tensai takes bricks back to their source with this incredibly detailed, colorful oil rig that uses countless LEGO pieces in surprising ways. The overall effect is one of large-scale industrial activity full of pipes and conduits, a helipad with brick-built lettering, numerous towers, cranes, and gantries — and even a multi-colored oil slick on the ocean’s surface. But clicking through to the builder’s full-size photo rewards careful examination, from the Technic pump behind the red and white crane to the single minifig leg and yellow parrot projecting below the helipad.
