Frequency

"Frequency is a poetry generator written in Ruby. The lines of all the poems in Frequency are constrained by the fact that I used only 200 of the most common English words in them. The poems generated by Frequency are built from a pool of 2000 lines I wrote. The web pages shown here are not the poetry generator itself, but were generated by the program. Frequency can arrange lines by a number of different constraints, including rhyme scheme, syllable count, and character count. The program outputs Shakespearian, Spenserian, Petrarchan, and Terza rima rhyme schemes, syllabic forms such as Haiku and Tanka, the Oulipan snowball form (by word, syllable, and character count), and a few invented forms, including 'Two Towers,' 'Foursquare,' and 'Doubling'. Ten different forms are included in the demonstration site, with 200 examples of each form. The generator itself is also included and can be run in a terminal window. See the source code for instructions." -- from Electronic Literature Collection, Volume 3
