    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.

with starry backdrop: for(i=2e3;i--;)x.fillRect(i,t*99,r=4.6*Math.random(),r);if(t<121/7) x.clearRect(960+320*C(t-(h=t>88/7?1:0)),540-320*S(h+t),6,6)
