Origami computer uses folded paper for calculations

By representing data as folds in paper, the principles of origami can theoretically be used to compute anything imaginable.

Paper folded according to the rules of origami can theoretically perform any computation imaginable, from adding numbers to running the latest artificial intelligence software, though in practice this is unlikely to be useful.

While we normally think of computation as something done using silicon chips, anything capable of representing and manipulating information can be used as a computer – for example, dominoes arranged in the correct pattern are able to add together two numbers.
