This program designed by Andrei Gheorghe is right up there with the most engaging and successful conceptual poetry projects I've seen to date.
Brandon Brown has been talking about prosody on his blog, and this project raises some resonant questions for me in that context: first of all, is prosody a useful term to describe a rhythmic and syntactic effect created not by one writer's sustained attention to sound as it unfolds through time, but by the randomly and mechanically generated rhyming of phrases from disparate sources? It's interesting how hard this effect is to tell apart from that of any of millions of "organically" produced poems by amateurs--or poems which mimic such work, like Ashbery's "Variations, Calypso and Fugue on a Theme of Ella Wheeler Wilcox."
