This topic brings back memories. When I was younger, I made a rudimentary cut up machine in qbasic that flipped around the current text entry and randomly injected entries from a five hundred word/phrase list. By the time I got tired of messing with it, I had subroutines that generated new lists as it was working. That way, not only did it make random cuts, it did them a random number of times, picking from, as the process went on, up to ten different files. It was strange, because every now and then, the program appeared to perform a blind sort and spit out lines and phrases that managed to congeal back into their original forms.
I haven't used an online cut up machine in years. I think the last one I played around with had, among other banked quotes, Ren and Stimpy's Log Song, which strangely enough slots in nicely with certain selections of Einstein and Hawking.
I'm still partial to doing them by hand. I made a cut up titled "Hopes" with random newspaper quotes regarding the election back in 2000. The one phrase I remember best from it was "an activist in a pink pig costume ordered and a foot of rain fell." I recorded a sound file of me reading the whole thing, layered with an electric guitar rendition of the star spangled banner behind it, but unfortunately that was lost to the ether three hard drive crashes ago. I did find some cut up and anti-writing files left on my backup drive though.
