cobra and game pieces instructions and scores

hi everyone i'm working on a collaborative real time / lag time internet audio game piece for my students (i teach in a fine arts school). It has no composing pretention and mainly focuses on the process As i'm setting up rules, i wish i had material and examples to show students such as instructions and scores such as used by john zorn on Cobra and other game pieces. would anyone have useful urls or ideas ? thanks in advance jean-philippe halgand pavu.com
