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:
“We are often made to feel that there is another youth and age than that which is measured from the year of our natural birth. Some thoughts always find us young, and keep us so. Such a thought is the love of the universal and eternal beauty.”
—Ralph Waldo Emerson (1803–1882)
