    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.

a quick paralx idea, ofcourse would been nicer filled in colors ;) wonder if it can be shorten enough for that.

If I look at the point, I see it coming out of the screen. But if I look at the back, I see it point away.
