Part 1 - Rolling a circle on a circle that's the same size.
Part 2 - Rolling a circle on a circle that's twice as big.
Part 3 - Rolling a circle inside a circle that's 2,3, or 4 times as big.
Part 4 - Rolling a ball on a ball that's 3 times as big: warmup.
Part 5 - Rolling a ball on a ball that's 3 times as big: conclusion.
