Universal Computer-constructor
Codd designed a self-replicating computer in the cellular automaton, based on Wang's W-machine. However, the design was so colossal that it evaded implementation until 2009, when Tim Hutton constructed an explicit configuration. There were some minor errors in Codd's design, so Hutton's implementation differs slightly, in both the configuration and the ruleset.

Famous quotes containing the word universal:
“Hail, Source of Being! Universal Soul
Of heaven and earth! Essential Presence, hail!
To thee I bend the knee; to thee my thoughts
Continual climb, who with a master-hand
Hast the great whole into perfection
touched.”
—James Thomson (1700–1748)
