    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.

It may have an integer overflowing problem with the angle. I couldn't wait that long to confirm it.

You could get rid of that for loop and make this into a slow loader instead but I think it's better this way. Also, my golfing skills are a mess.
