This is a fun program with a wide range of choices such as Haiku, Fortunes, Bureaucratese, Insults (my favorite), Blessings (which sound disturbingly similar to insults, TVGuide, Definitions, ArtSpeak (very similar to the BS I heard and read in college-level art classes), and more. Amazing little program, prettier than McPoet, and now, of course, OSX-capable. Easy to use, but with a 70-page manual if you really wanna delve deeply into it.
And if you pick the very best things it generates, you can get some good stuff. Two of my favorite definitions generated by JanusNode:
spiritual rhythm: perceptible eccentricity
wind: eagle's egocentric euphoria
