i've always been interested in systems and their relation to creativity -- partially because i tend to work in series and with collage, but also because i think that creativity really shines when we are given limits to work within, push against, transcend. in fact, it's a great way to develop your "chops" - working with different styles, genres and other limitations. certainly, utilizing forms and structures as generative devices is not new, nor is it a new thing to incorporate randomness as part of the process.
and while you're there, you may also want to check out glitch. just sayin'...
