    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Golfing u/BuRRak π calculation using Nilakantha's series

Alternatives are: 33 chars using Wallis product but *very* long time to converge. 24 chars using Newton-Raphson if sin & cos allowed.

Hey hg, BTW, I deleted your Zelda sound dweet because we're trying to apply the policy of not playing unsolicited sounds. (It's still acceptable to play sounds on user interaction.)
u/AnnanFay

I added the http because I thought it would turn it into a link. Probably should have just linked http://具.pw/about.html

@magna, apologies. I did think it was a bit annoying.
