It took Richard Ridel six months of tinkering in his workshop to create this contraption--a mechanical Turing machine made out of wood. The silent video above shows how the machine works. But if you're left hanging, wanting to know more, I'd recommend reading Ridel's fifteen page paper where he carefully documents why he built the wooden Turing machine, and what pieces and steps went into the construction.
If this video prompts you to ask, what exactly is a Turing Machine?, also consider adding this short primer by philosopher Mark Jago to your media diet.
