Chance Operations-"Boys and their Balls"

I completed a sound project using chance operations.  For those who don't know, chance operations is a process art.  Process art is where the process is more significant than the final result.  In the case of chance operations, something is left to chance in the process, therefore leaving the artist with little control of the result.  

I placed 8 young men into a room, one at a time.  All there was in the room was a single ping pong ball, some wooden box stands (for presenting gallery work) and a couple screws and nails (of which i never purposely placed in the room, the 3rd subject found the nails/screws during his boredom).  I recorded them for five minutes each, told them they could do whatever they wanted in the room besides touch the microphone.  I took their cell phones and mp3 players away so they wouldn't distract the subjects.  

I took all their individual recordings and overlayed them using audacity.I was hoping to have some sort of unified rythym or climactic period similar in all 8 recordings.  None of which happened.  Some subjects didn't even touch the ping pong ball or nails.  Some moved the boxes to make a makeshift bed (lazy a-holes since it was only 5 minutes!).  If i were to do this project again i would do it in a smaller room, with nothing but a ping pong ball...and maybe even for a longer amount of time.  Overall I am satisfied with my process even though the final product isn't as spectacular as I would of liked but, I guess thats just a part of chance operations.
