Bletchley Park, a sprawling estate in Milton Keynes, England, has been called the Intelligence Factory. It was home to the Allied codebreakers during W.W. II, a brilliant group that included Alan Turing. Today the site is world renowned, but the war work that happened there was kept shrouded in secrecy until the 1970s. It was only then that the existence of Colossus, a set of computers developed to break the Axis code, was revealed. A new exhibition takes us into this world of data, showing us how the codebreakers visualized it. With 3D animation and interactive screens, contemporary examples of code are explored. —Elena Clavarino
