A pretty deep improvement of my recent KOTMK entry, markovlove360 uses all the works sent into http://loveblender.com/ in 2004 to create a web community / computer /human collaboration tool, using markov chains for statistical textual analysis as the basis for computer-augmented lyrical composition.
Simply move the mouse to highlight the next word you want, and click to select. The most recent 2 words selected define what options are available for the next word; those options are the set of words that followed that word pair within the body of work from the blender, scaled by frequency (the more often a word followed a word pair, the larger its piece of the pie.)
"S" saves the current work to a text file in the same directory, "C" clears the page, and "R" sets a Random Robot to do the selection for you
