Alan Turing, considered the founding father of computer science, conceived of the Turing machine to illustrate mechanical computation in 1936. Although deceptively simple, the device can model more complex computer algorithms. Jeroen van den Bos and Davy Landman at Amsterdam's Centrum Wiskunde & Informatica set out to honor Turing's legacy by recreating his calculating machine with LEGOs. This short video from Andre Theelen demonstrates how the colorful plastic pieces can tackle a problem like adding two plus two.
