In 1936, Alan Turing imagined an abstract model to define what used to be an intuitive notion: the calculability. This model is today known as the Turing machine and is still used in theorical computer science to solve calculability problems.
At the occasion of Alan Turing's centenary, Masters students in fundamental computer sciences of the "Ecole Normale Supérieure", located in Lyon (France), pay homage to him through the building of a Turing machine in Lego.
