I'm working on a simple little utilty for finding and exploring internal rhyme schemes in poems and songs. I made this in order to better show people just how complex a rap artist's rhyme combinations can get. You can view my work in progress online at http://reasonedrhymer.com (Click on a combo or word to filter the results)
