We've just added two new runnable ELIZA adaptations to the ElizeGen collection. One is Steve Cherry's Apple II P-Lisp ELIZA, c. ~1980, put online by Ron Garret. (This one's been around for a while.) The other (brand new ... well, brand old :-) is one built in HyperCard by Brendan Bellina, and runnable through infintemac.org. I highly recommend trying Brendan's version as it speaks its respones and the natural stupidity of ELIZA, combined with :yoda mode and the hysterical voices absolutely kills!
