Chains of dominoes can be set up to represent logic gates and circuits, and are capable of "processing" information to give a result. Mathematician Matt Parker currently holds the record for domino computing, having built a computer out of more than 10,000 dominoes that successfully added binary numbers. The computer could take two 3-bit inputs and produce a 4-bit output, making it a 4-bit adder.
