    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.

Playing it safe on the arc angle, modding it by 2pi just to avoid the bug on Safari.

Huh nice
u/joeytwiddle

Scrolling instead of switching: for(c.width|=j=15+t|0;j-->t;)for(g=(j-t)*180,i=99;i--;)x.fillRect(i?g+i*S(1e3/i-t*8+j**3):g,600+!!i*i*5,-99-80*S(j*j),i?3:-600)

What is this supposed to be? I only see black squiggly lines..
u/joeytwiddle

I think it's supposed to be buildings reflect in water. for(c.width|=j=20+t|0;j-->t;)for(g=(j-t)*120,i=W=99;i--;)x.fillRect(i?g+i*i/70*S(1e3/i-t*8+j**3):g,500+!!i*i*4,-W-80*S(j*j),i?3:-300-W*S(j))
