If you’ve seen the 2014 thriller The Imitation Game, you’re familiar with how Alan Turing ended up building essentially the world’s first computer (if you haven’t seen the film I highly recommend it). The Turing Machine was the theoretical predecessor to that computer (called the Bombe), which helped the Allied powers win World War II.
A #LEGO genius managed to build the first fully operational Turing Machine entirely using LEGO bricks.
