    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.

I use 44 longitude lines so the arc angle between adjacent two is 2*pi/44 which is approximated by 1/7 to 4 decimal places.

Using the famous pi ~ 22/7 approximation.
