There you have it. Still a long way to go before we could call these outpourings poetry, though a tour of computer-poetry sites on the web suggests that the state of that art hasn't advanced very much since 1976*. Indeed there are some human poetry sites where Gribbly's rambling verbal effusions wouldn't be disgraced. When I learn more about Javascript I hope to come back with an improved version.
[* Note added June 2023: BARD and GPT-4 have recently advanced the state of the art in computer poetry. The results almost always lack real poetic quality, but they are often better than most common or garden human offerings.]
