Ever year, Matt Parker calculates pi, and this year it was the largest manual effort to calculate pi in a very long time[1] . I took part this year, though I didn't end up in the video sadly. It was lots of fun though, and a nice trip to london [1] https://youtu.be/LIg-6glbLkU

DO seems to have some fun today as well :) https://twitter.com/digitalocean/status/576739557854425088
