    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.

another take with(x)for(r=960,j=65;j--;fillRect(...d))setTransform(2,0,0,1,960,400+4*j),rotate(t),strokeRect(...d=[r,r,r*=-2,r]),fillStyle=R(64,3*j,r=99)
