    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.

Calculating #pi based on a formula I found in a Commodore 64 manual. Googling says it's the Gregory-Leibniz series.

I thought I'd see if I can calulate PI in 140 chars. Math.PI is 3.141592653589793, which is 15 decimal places. 15 decimal places is precise enough to calculate the circumference of the solar system (including Pluto) with an accuracy of a meter. The formula is Nilakantha's from the 15th century. You could also just print 245850922/78256779 but doing that doesn't seem much better than just printing Math.PI.

I'm not sure that counts as storing digits of pi, but I'm already impressed you managed to get this down to 68 characters :P

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