i had an idea i wanted to put under this term last night, and googled, and the result isn't exactly what i was thinking though its interesting. it seems like people are building lyrics into their source code, such that said source code produces some kind of evocative, related image
what i was thinking was more like... generating imagery, but providing the source code as a way of letting the process of that imagery's generation be meditated upon. not explicitly building in story or metaphor through human language, but instead letting the process of producing the image tell some kind of story. think i might try that soon.
