The OCA Discovery of the Year[note 1] (OCADOTY) competition is held each year on the ConwayLife.com forums as a counterpart to Pattern of the Year dedicated to rules other than Conway's Game of Life. Users are invited to submit interesting and noteworthy patterns, rules, families of rules, or projects relating to other cellular automata, their own or others'; following discussion, a final list is then curated, and a public vote held. All entries must have been found during the year in question.
Results by year
