This was originally meant for pi day 2024 but I released it just a little bit late... Hover mouse near top of screen to adjust speed. Numbers are rounded pretty quickly since scratch rounds numbers to ~20 digit so many of the calculations aren't very precise. The Nilakantha formula was giving incorrect digits earlier because I added 3 to an index instead of 2. Fixed now.
Credit to all of the people who discovered how to solve for π since I definitely could not do this.
