Raymond Queneau famously kicked off the Oulipo with his Hundred Thousand Billion Poems. This set of ten sonnets had each of it's 14 lines divided up such that there were 100,000,000,000,000 different possible poems. Each line has the same rhyming scheme and the same rhyming sounds so they can be arranged in any combination. Pretty groovy.
You can find a link to an interactive, online and exciting version here. Each possible combination even has a serial number. This is an exciting way to use the internet to completely destoy the romance of a beautiful piece of well-considered and written work.
