    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.

If there's a short way to move the entire drawing a few pixels, it would allow quite a bit more room for messing around...

Bring out q to shave off two: s=7,x.drawImage(c,q=t?0:a=[l=1],-s)
