Follow the Ball

The curator of our art gallery was an unusual man. He would only eat hard-boiled eggs, preferred his coffee almost freezing cold, and, before he died, he started a collection of children's sing-along videos, the kind where you had to follow the bouncing ball. He would watch them day and night, looking for patterns, becoming very disagreeable if interrupted for any reason. After his death we found this page among his things. Maybe you can make some sense of it.
