Rhymatron.net has officially launched BETA! (4/30/2010)
The Rhymatron Python project has finally launched on a working website. Behind the scenes, the web server is running a Python script to pre-generate enormous lists of rhyming words and rhyme keys. Then a user selects from a list of pre-fabbed templates (or creates their own) and the poem/rap output gets spit out. Rather than this output being static, instead the user can adjust any word by clicking up and down arrays to cycle through other words from that same rhyme key list. A word that is intended to rhyme will continue to rhyme, even when it has been replaced.
