soft question - How many different representations of pi can we come up with?

Let me explain: a friend of a friend is opening a new pizza restaurant called "Pi", and he's looking to decorate his walls with pi-related material: formulas, equations, theorems w/ proof, diagrams, etc. Any suggestion is welcome, so long as it meets these two criteria:



  1. It has to be mathematically correct.

  2. It has to be either a representation of pi itself or lead directly to a representation of pi.

So for example, this is okay: suminftyn=1frac1n2 (because it equals fracpi26)
But this is not: frac227.



How many can we come up with?
