Matt Parker and a team of Domino Computer Builders balanced over 10,000 dominoes in a carefully designed circuit. The result was a Domino Computer capable of automatically adding numbers. It can take any two four-digit binary numbers and return the five-digit binary sum.
It's a computer, made of dominoes.
