I was in the common room today, and a hockey game was playing on T.V., as usual (nobody was watching it). I looked at it for a very short while and thought to myself,
"If you used something to track the location of the puck for the whole game and then created an image based on its path, you could make art!"
...and then, just now, while putting this up, I realized that if you did it for soccer or some other sport you could apply some other attribute (colour, opacity, brightness, etc) to the height of the ball, which would make it even more awesome. Something could also probably be done by tracking the locations of the players too, but that starts to get tough, and very crowded.
What kind of art would this be classified as?
