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:
“Music is the sound of the universal laws promulgated. It is the only assured tone. There are in it such strains as far surpass any man’s faith in the loftiness of his destiny. Things are to be learned which it will be worth the while to learn.”
—Henry David Thoreau (1817–1862)
