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!

I want to say avant-garde and 1930s, but I don't know why
u/taupelink

Hints of "Metropolis" maybe? (1927 but close enough).
