Possibly the first computational poetry generator. Poems by the generator were published in Horizon Magazine and possibly in Time Magazine in 1962.
"Librascope engineers, concerned with the problem of effective communication with machines in simple English, first ‘fed’ an LGP 30 computer with thirty-two grammatical patterns and an 850-word vocabulary, allowing it to select at random from the words and patterns to form sentences. The results included “Roses" and “Children". Then Worthy and his men shifted to a more advanced RPC 4000, fed with a store of about 3,500 words and 128 sentence structures, which produced … more advanced poems."
