    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.

It looks similar to my previous demo, but now it is not compressed!

The music slowly changes over time and will not stop on its own. This is a new idea combining the oscillator setup with byte beat music to allow for enough space to write graphics code!

uncompressed... t?t*=60:o=(a=new AudioContext).createOscillator();q=o.frequency.value=(t&t<<4^t)%897;x.fillStyle=R(q%255,0,q/3);x.fillRect(t%2048-q/2,q,z=t?q:2e3,z);o.connect(a.destination);o.start();

Sorry username, I know it is loud and may play automatically in firefox! (even though it shouldn't) I won't be posting any more music for a while so you are safe (for now).
