    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.

note to future self... this is some kind of weird combination of interference patterns between waves, and circle-squares fractals ....to see whats going on, start out with fillstyle=R(B%256,0,0) then work from there.
