Do the sprinklers interact? (as in one sprinkler setting off some kind of a trigger - perhaps as simple as a toilet-type valve - which starts or stops another? A few years ago I saw several works by an artist who had balls rolling/bouncing/flying through a 3-dimensional wire maze with random elements in which accumulated balls in a trap would trigger other ball actions. It was great fun to watch.
