Domino computer

An OR gate built from dominoes, with the bottom left and bottom right dominoes as its inputs and the top domino as its output. If the bottom left or the bottom right domino is pushed (or if both are pushed), then the top domino will fall; if neither is pushed, it will not fall.

A domino computer is a mechanical computer built using dominoes[1] to represent mechanical amplification or logic gating of digital signals.[2]
