    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.

American flag. Initialy I attempted it with a blue rectangle on top of which I added white rectangles for the stars, but I couldn't get it short enough. This looks way worse, but it's also way shorter. Would be curious to see if anyone can get a better looking US flag in this space.
