function u(t) {

    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.

x.fillStyle="#fff3";x.fillRect(0,0,c.width,c.height);for(i=192;i--;)for(j=9;j--;x.fillStyle=hsl(${h},50%,50%))x.fillRect(i*10,h=540-(S(t*2+i*3.12)*C(t+i+j/9)*j/4)*100,10,10)

Or, replace c.width^=0 with x.fillStyle="#fff3";x.fillRect(0,0,c.width,c.height);

Abstract smoke! Nice! Could look nice if it left a trail?
u/joeytwiddle

Tried shadowBlur but very heavy. Trails look better anyway: x.fillStyle='#fff3',t?x.fillRect(0,0,999,800):c.width=999;x.beginPath();w=540,t?m=[w+S(t)*340,w]:p=[];p.push([[...m],5]),p.map((z,i)=>{k=z[0],k[0]+=S(i+t),k[1]-=z[1]+S(i*8),x.lineTo(...k),x.stroke()})

Oooo, I like that, great idea! I'll have to try incorporating that into a remix. Thanks joeytwiddle!

You've reached the end.
