For sheer too-excited-to-eat-breakfast thrills, you couldn’t beat tumbling down the stairs of a birthday morning to find a bloody big, rattly box of Technic LEGO waiting for you. Just pray it wasn’t a school day. The hours would just fly by as you knelt, elbow deep in the most advanced children’s construction set ever, replete with working piston engines, pneumatic hoists, chunky, steerable rubber wheels and – if you were lucky - a working motor. By evening, you’d be driving around a custom dune buggy fork lift truck some seven feet in length. Or so it seemed.
