For Pi Day 2016 I tried to calculate π by hand, using an infinite series. It goes ok.

Before you even start:

- Yes, I know π Day requites writing the date MM/DD. By objective measures: the wrong way. I don't care. My love of π is stronger.

- My opinion of Tau is a matter of public record: /youtube/video/ZPv1UV0rD8U

CORRECTIONS:

- At 17:23 it should be π/4 not 1/π. That was contamination from the next graphic. (First spotted by Najeeb Sheikh and Jake Trookman.)
