Ah, thanks.
I used Eliza as a kid, was pretty fun at the time. Later, on a 286 IBM PC, I found a program called "Babble" that was really amazing. It learns word patterns as it goes, I believe it uses Markov chains, and over time improves its responses. It also had a lot of speech filters, such as "Pig Latin", "Stutter", "Elmer Fudd", etc. Fun times for a kid!
