What does this picture best illustrate?

\sum_{n = 0}^{\infty}\frac{1}{n^2} = 1

\prod_{n = 1}^{\infty}\frac{1}{n^2} = 1

\sum_{n = 1}^{\infty}\frac{1}{2^n} = 1

\sum_{n = 1}^{\infty}\frac{1}{n^2} = 1

\prod_{n = 0}^{\infty}\frac{1}{2^n} = 1

\prod_{n = 1}^{\infty}\frac{1}{2^n} = 1

\prod_{n = 0}^{\infty}\frac{1}{n^2} = 1

\sum_{n = 0}^{\infty}\frac{1}{2^n} = 1
