    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 have seen this pattern (circular horizontal lines with a stronger single vertical curved line in the middle) emerge in some recursive functions with a parameter increasing it's value ("-t" in yours). I will post here one that I created with this pattern.
