    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.

Basically the same thing but in 40: for(i=3e3,t*=99;i--;)x.fillText(1,t|i,t)
u/Xen

37 but not as good: for(t*=i=1e3;i--;)x.fillText(i,t|i,t)
