Some courses on sources for text sources, of courses!
Given some valid (intelligent) text as input only, the software generates new randomized text that is based on the proportion of characters in the seed text that are next to other seed text characters. (Th, st, qu, and so on. Like the freq tables that Wheel of Fortune players usually have memorized.) Using recursion, this software can come up with some pretty cool discussions... meaningless, of course.
