    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.

120 chars for more room to play: r=Math.random;with(x)fillStyle=hsl(${r()*360},90%,77%,filter='blur(1px',fillRect(r()*2e3,r()*1e3,1,1),drawImage(c,0,0)
