Contemporary logic circuits use MOSFETs as the elements to build gates, but there are many ways to implement them. Using relays is one of them, and you can literally see how they work.

this teaching tool allows different logic gates to be wired together with patch cables. While [David] first thought to use 74-series logic circuits directly, a much more versatile solution was to ...
