Making a Turing machine is a kind of nerd rite of passage, like manually editing your X11 settings or building a two-second time-machine. As far back as 2005, we were chronicling the adventures of Lego Turing-machine builders (the state of the art advanced rather a lot by 2012), as well as the ongoing effort to attain Turing completeness in wood and also baked goods.
Here's the latest iteration, a Lego Turing machine created by comp sci Masters students at the Ecole Normale Supérieure in Lyons, which comes with its own 7 minute documentary.
