    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.

Oohhh nice remix. I always say it as the fish was swimming out of the screen towards the viewer ^^

You can try it: c.width=-1;for(j=2e3;j--;x.fillRect(99+9*S(a=j/1250)*S(j)+50*S(m=t*3+a),75+25*(S(-a*5)+1)*C(j),3,7))x.fillStyle=R(q=(j&128)-C(j)**3*99,q,q)

sorry, wrong code, I meant c.width=-1;for(j=0;j++<2e3;x.fillRect(99+9*S(a=j/1250)*S(j)+50*S(m=t*3+a),75+25*(S(-a*5)+1)*C(j),3,7))x.fillStyle=R(q=(j&128)-C(j)**3*99,q,q)
